Advanced optical-fibre sensor systems designed for structural condition monitoring Professor Kenneth GrattanDean, City Graduate School, Royal Academy of Engineering, George Daniels Professor of Scientific InstrumentationCity, University of London, London, UK

Optical Fibre Sensors have been developed extensively over the last thirty years, but in recent years important applications of these systems have been developed to meet a range of challenging industrial applications. The civil and structural engineering industries have been aware of the need for better monitoring of the multi-billion dollar civil infrastructure around us, whether it be bridges, buildings, towers or other critical parts of what makes modern towns and cities function well. This talk will review the background to optical fibre sensors, especially those using Fibre Bragg Gratings as their technological basis, and consider a number of applications where researchers at City University of London have been involved in creating new solutions to topical problems in structural condition monitoring, be it in Europe, Asia or Australia.

Integrated photonic smart sensors Professor Benjamin J. EggletonDirector, Centre for Ultrahigh bandwidth Devices for Optical Systems (CUDOS), Australian Institute for Nanoscale Science and Technology (AINST), NSW Smart Sensing Network (NSSN)School of Physics, University of Sydney, NSW, Australia

Integrated devices are everywhere: chip-scale electronic processors in our phones and computers now penetrate every aspect of our lives; optoelectronic devices enable ultrahigh bandwidth data networking, thus sustaining the Internet’s constant growth; on-chip acoustic devices that exploit phonons (the sound-wave analogue of photons) underlie small radio frequency filters in mobile phones and can exert very strong forces to move fluids and mix chemicals in lab-on-chip devices. To achieve maximum impact on our lives, the next great challenge is to develop integrated devices in which these three complementary physical phenomena work together. By accomplishing the tight integration of all three classes of wave onto a single platform, this new class of chips will reach out to the world, becoming active devices that sense, analyse, respond to, and manipulate their environment. This revolutionary approach to integration presents an opportunity for unprecedented control over matter, energy and information. It will enable new and disruptive technologies that will significantly impact on our national priorities in health, cybersecurity, advanced manufacturing, energy, food, and soil and water.

Plenary Session I

SESSION I: ADVANCEMENT IN FIBRE-OPTIC AND PHOTONIC SENSORS Monday 9 January 2017 AEB - Auditorium

Recent progress in fibre-optic sensors for industrial and safety applications Professor Yun-Jiang RaoDirector, Key Lab of Optical Fibre Sensing and Communications,University of Electronic Science and Technology, China

Based on many years of research, a number of novel fibre-optic sensors and systems are developed by the Fibre Optics Research Centre (FORC) at the University of Electronic Science & Technology of China (UESTC). This presentation will present an overview of the recent advances made by FORC in fibre-optic micro-cavity F-P sensing systems for high-temperature strain sensing and pressure measurements, and distributed fibre-optic sensing systems for long distance remote strain/temperature/vibration measurements. Applications for these fibre-optic sensing systems have been demonstrated in aero-industry, safety monitoring of undersea electrical powerlines and fibre-optic communication cables in electrical industry, and oil exploration and safety monitoring of oil pipelines in oil industry, which would provide revolutionary technologies to solve the high-temperature and long-distance challenges in aero- and electrical/oil industries, respectively.

Fibre-based devices and sensing applications Professor Perry Ping ShumDirector, Centre for Optical Fibre Technology, School of Electrical & Electronic Engineering, Nanyang Technological University, Singapore

Optical fibre-based devices have been widely deployed in recent years. There are many advantages of using fibre as a sensor. These include electrically-passive operation, light weight, immunity to radio frequency interference and electromagnetic interference, high sensitivity, compact size, corrosion resistance, easily multiplexing and potentially low cost. Several novel fibre-based sensors and technologies developed are presented here. These include fibre Bragg grating (FBG) based sensors, photonic crystal fibre (PCF) based sensors, specialty fibre-based sensors and distributed fibre sensing systems. FBGs as instinctive sensors, are ingeniously designed as two-dimensional (2D) tilt sensors, displacement sensors, accelerometers and corrosion sensors. Here, PCF based evanescent field absorption sensors, PCF induced Mach-Zehnder interferometer and Fabry-Perot refractometer for temperature and refractive index sensing are presented. Based on the localized surface Plasmon resonant (LSPR) effect, nano-sized fibre tip with gold nanoparticles are demonstrated for live cell index bio-sensing applications.

The monitoring of underground coal mine environments – the need for fibre optic based sensing systems Professor David CliffSustainable Minerals Institute, UQ, Australia

The capacity to monitor the environment of underground coal mines is vital in the prevention and control of harm to mine workers. History is littered with deaths due to fire, explosion, inundation, outburst and strata failure. Much progress has been made since the days of the carbide lamp, the canary and the flame safety lamp. However, current mine environment monitoring systems have significant limitations and do not routinely involve the use of fibre optics. Real time gas sensors require power. Most of these sensors need oxygen to assist in the electrochemical reaction of the sensor and are only available for a few gases. In addition, every sensor needs to be intrinsically safe, protected from the harsh environment and calibrated individually to be used in underground coal mines. Tube bundle systems which extract the gas for analysis on the surface suffer from the time delay to get samples to the surface. In addition, other parameters such as temperature, pressure and air flow are not routinely monitored. Over the ages there have been many attempts to use fibre optics to improve this situation. As far back as the 1980’s there was a fibre optic system for the detection of methane trialled in NSW. Since then there have been various attempts to develop systems for sensing methane and hydrogen. This paper will discuss the current situation, identify the needs and discuss the barriers to using fibre optic systems to improve the monitoring of underground coal mines.

Advance of optical fibre sensors for detection of major coal mine hazards Professor Tongyu LiuLaser Institute, Shandong Academy of Science, Jinan, Shandong, China

A number of health and safety hazards exist in underground coal mines, which include methane gas explosion, coal combustion and rock roof collapse flooding. Methane gas and coal combustion have been the two major hazards causing most of the heavy casualties and economic loss. Conventional catalytic methane gas sensors suffer from poor accuracy and cumbersome maintenance, which is the bottleneck of methane hazard prevention. Coal mine combustion monitoring has been relying on a gas tubing bundles system, which suffers from long time delay and poor reliability. Semiconductor laser diode methane gas sensors have been developed which are characterised with low power consumption, 0-100% full detection range, high accuracy, and no need for recalibration in theory. Fibre optic Raman distributed sensors have been deployed in a coal mine goaf and successfully detected combustion hazard in early phase. In this presentation, a number of hazard prevention cases will be reported, and the progress of fibre optic multi-gas sensing will be presented as well.

Reliability of FBG sensing system for industrial and safety applications Professor Weimin ChenSchool of Optoelectronic Engineering, Chongqing University, Chongqing, China

Due to its distinguished advantages, Fibre Bragg Grating (FBG) sensing technology has been widely used in industrial and safety applications, such as civil engineering, power engineering, mechanical engineering, and etc. As the sensory organ of industrial facilities, any failures of FBGs might lead to serious consequences. According to some statistics, more than 40% of industrial serious accidents have been traced to the failures of sensory system. Therefore, reliability and service life becomes the most concerned features of FBG sensing system for industrial and safety applications. This talk will overview the 10 years’ research activities done on the reliability of FBG sensing system at Optoelectronic Lab of Chongqing University. In terms of sensing element, performance degradation of FBGs under bad working environment will be discussed. Side effects of bonding layers on the reliability of packaged FBG strain sensor will be also presented. With regard to signal demodulation, the degradation of FBG is evaluated based on its reflecting spectral analysis, and adaptive demodulation algorithm is presented to accommodate the degraded FBG sensors. Some examples for upgrading reliability of FBG sensing system will be also introduced.

Walkaway VSP using multimode optical fibres in a hybrid wireline Professor Gang YuSenior Technical Advisor to the President, BGP Inc, China National Petroleum Corporation, China

Distributed Acoustic Sensing (DAS) is a novel technology that uses an optical fibre cable as a sensor for acoustic signals. DAS is able to take almost any downhole fibre-optic installation or deployment and turn the fibre-optic cable into a large downhole seismic array. This array can provide enhanced vertical seismic profile (VSP) imaging and monitor the fluid and pressure changes in the hydrocarbon-production reservoir. Walkaway VSP data acquired over a formerly producing well in Northeastern China provided a rich set of high-quality DAS walkaway VSP data. A standard VSP data pre-processing workflow was applied, followed by prestack Kirchhoff time migration. In the DAS pre-processing step, we faced additional challenges: strong coherent noise due to cable slapping and ringing along the borehole casing. Compared with an earlier offset VSP data set using 327 levels acquired with conventional 3C downhole geophones in the same well, the final pre-processed DAS walkaway VSP has a larger vertical aperture, resulting in a wider lateral image. The single-well DAS walkaway VSP images provide better results with higher vertical and lateral resolution than the surface seismic in the objective area. The vertical-well environment, which lacks the ability to effectively “clamp” the sensor to the borehole-casing wall by touching, causes a unique set of challenges. Although earth signal was recorded with almost all the shots, there was also a considerable amount of noise. Reported here are the lessons learned in handling the wireline cable and subsequent special DAS data processing steps developed to remediate some of the practical wireline deployment issues. Optical wireline cable as a conveyance of fibre-optic cables for VSP in vertical wells will pave the way for the use of the DAS system to a wide range of applications.

Photonics in smart sensing networks Professor John CanningInterdisciplinary Photonics Laboratories, The University of Sydney, Australia

Smart device technologies are revolutionising diagnostics for sensing across medical, agricultural, industrial, consumer and many other industries. Photonics is almost certainly set to play a role either incorporated with or integrated in the lab-in-a-phone vision. In early days, the integration of photonic components has been limited to optical components such as LEDs; but inevitably the smart device platform will absorb future optical and quantum chips once they come on line. The massive consumer market, which is producing stunning electronic devices at historically low costs, is particularly interesting. I anticipate the same drivers will bring photonics costs down by similar margins although the fabrication technologies need to do substantial work in this area. In this presentation I review our entry and subsequent communication of this field, pioneering Australia’s efforts and discuss the potential for Australian industry, including new start-ups that exploit these technologies today and into the future.

High sensitivity gas sensors based on photothermal interferometry with hollow-core optical fibresProfessor Wei JinDepartment of Electrical Engineering, The Hong Kong Polytechnic University, Hong Kong

This presentation reviews the basic principle of photo-thermal spectroscopy and reports the recent developments of photothermal gas sensors with hollow-core optical fibres. Theoretical modelling on the dynamics of photothermal phase modulation in both hollow-core microstructured optical fibres and open-path free-space systems are conducted. Experiments with CW and pulsed sources for photothermal excitation are carried out with various interferometer configurations for phase detection. Femtosecond laser-drilling of hundreds of low-loss microchannels (<0.02 dB per channels) along a hollow-core microstructured optical fibre is also demonstrated, which enables fast response (e.g., 30 seconds) gas sensors with very high detection sensitivity (ppb level). Gas sensors with such levels of performance would be useful for a range of applications such as environmental and safety monitoring, industrial process control and medical breath analysis. Future trends of developments of photothermal optical fibre sensors will also be discussed.

Fibre-optic biochemical sensors: opportunities and challengesDr Yinlan RuanThe University of Adelaide, Australia

The intrinsic property of optical fibres to conduct light to a remote location makes them an ideal platform for point-of-care diagnosis and in vivo biochemical sensing. By integrating functionalized materials into the fibres, miniaturized and advanced all-in-fibre probes can be realized for environmental monitoring, life science, food safety and security applications. Light-matter interaction on the fibre is achieved through fluorescence, surface plasmon resonance or whispering gallery modes of the functionalized materials which are highly sensitive to local modifications of surrounding environment. Surface chemistry and the related functionalization protocols play an important role for reliability and reproducibility of the optical fibre chemical sensors.

Application of fibre-optic sensors for the minerals industryDr Fernando VieiraProgram Leader, Mining3, Australia

The minerals industry is being challenged to become a digital industry in order to benefit from technological advances, available to other industries that make use of sensor-based data to enhance predictability. One such challenge is the ability for capturing seamless and spatially-distributed real-time responses of processes, involving the interactivity of equipment and material movements under varied operating environments. Up to recently, mining sites have made use of mechanical-electronic type technology sensors, including kinetic, thermal, vibration, acoustic, hydraulic, etc., to monitor relevant phenomena or specific activity that impact on the conditions of operability, efficiency, and safety of mining ventures. There are phenomena and operational spatially-distributed events that can be monitored using fibre-optics-based sensors. Such applications, their constraints and benefits, including the likely scenarios of operability, and ultimate their industrial value, will be discussed.

VCSEL photonics for optical sensingProfessor Fumio KoyamaTokyo Institute of Technology, Japan

Our recent activities of VCSEL photonics toward optical sensing applications will be presented. We propose and demonstrate a VCSEL-based high-resolution beam scanner with optical amplifier function, which will be useful for optical sensing applications such as LiDAR and bio-medical imaging. We address a lateral integration platform and new functions, including high-resolution beam scanner and optical amplifier. The structure of the slow-light waveguide beam steering device is similar to a conventional VCSEL in the vertical direction. An active region is sandwiched by two distributed Bragg reflectors (DBR) as mirrors. A portion of light radiates from the surface. Thanks to the large angular dispersion, we are able to realize high-resolution beam-steering of the radiated light by tuning wavelength. We achieved a record number of resolution points larger than 1,000 among non-mechanical beam scanners.

Distributed fibre optic sensors for detecting fires and hot rollers on conveyor beltsDr Henrik HoffBusiness Director, AP Sensing GmbH, Germany

The use of modern fibre-optic sensors based on DTS (distributed temperature sensing) technology has been proven as a method for fire detection and temperature measurement. A passive fibre optic cable provides accurate temperature measurements along the length of the conveyor belt, which enables an effective and cost-effective monitoring of even very long conveyor routes. Fires and overheating, which can occur during operation and lead to serious damage and long downtimes, are quickly detected and localized to within one-meter accuracy. The necessary countermeasures can be quickly activated. Heat detection for hot rollers requires a proper installation of the sensor cable and configuration of the alarm zones and analyses. This paper is based on conveyor belt tests and case studies, and describes the potential of fibre-optic based DTS technology with regard to fire and hot-roller detection along conveyor belts.

We developed a fibre sensing system that is electronically passive, i.e. no electronics downhole, and can continuously monitor downhole pressure and temperature of oil wells under production without disruption. The system has high sensitivity of 220nm/MPa and accuracy of ±0.05%F.S. The system has been installed and tested in a production well monitoring the downhole temperature and pressure for a year. At temperatures up to 140°C and pressures up to 50 MPa in the well, differences within 1°C and 0.03 MPa, respectively, are achieved in comparison with a commercial electronic pressure sensor in an experimental well. We will also report and discuss some of the remaining issues in downhole applications.

Fibre optic seismic sensor for down-well monitoring in the oil industryProfessor Min ZhangInstitute of Ocean Research, Peking University, Beijing, China

Development of unconventional oil and gas reservoirs, especially the shale gas, has attracted great interests in recent years. And hydraulic fracturing in combination with the monitoring and interpretation method is the key technology to make the development of these reservoirs an economic reality. As China is rich in unconventional oil and gas, particularly heavy oil, extra heavy oil and tight oil, oil companies in China paid much attention to the hydraulic fracturing technology and its related monitoring methods. Among all the monitoring methods, seismic sensing based on fibre optic interferometric technology is highly valued for the sensors can be permanently fixed down the well. In this paper, we introduce the basic requirement of hydraulic fracture monitoring in Xinjiang oil field during the process of heavy oil exploitation. Then according to the requirements, we introduce both the all fibre optic monitoring technology and optic/electric composite monitoring technology. We also present the data interpretation and analytical results of the Xinjiang oil field experiments. In the end, we make a conclusion about the fibre optic seismic technology and its application in the exploitation of unconventional oil and gas in China.

Phase-extracted optical reflectometry for distributed vibration sensingProfessor Xinyu FanShanghai Jiao Tong University, China

Distributed fibre-optic vibration sensing based on phase extraction from optical reflectometry is discussed in this talk.

With a good understanding of the phase extraction noise in the phase extraction process, together with using a statistic analysis to solve the problem of existing measurement dead zones, long-range non-dead-zone distributed vibration sensing techniques with linear response to external vibration signals based on phase extraction from optical reflectometry are realized.

Aircraft structural health monitoring using laser and fibre opticsAssociate Professor Jung-Ryul LeeDepartment of Aerospace Engineering, Korea Advanced Institute of Science and Technology, Daejoen, Republic of Korea

Various structural health monitoring (SHM) systems based on laser ultrasonics and fibre optics are introduced. The systems are used to realize the new SHM paradigm, called Smart Hangar under the ground SHM scheme. Ultrasonic propagation imaging (UPI) is implemented in Smart Hangar in the form of built-in and mobile UPI systems. The laser ultrasounds generated in the wings and fuselage of an aircraft are captured by a fibre optic, piezoelectric or laser sensor and its propagation is visualized based on scanning mechanism. The wave propagation videos are further processed to visualize the damages. For in-flight SHM, laser scanning-based smartilization of the structure with sensors is presented and event localization method based on fibre optic and piezoelectric sensing is also introduced. The fibre optic sensors are also utilized to reconstruct the wing deformation. The wing deformation and impact localization information is transferred to a ground pilot in case of UAV and the ground pilot can feel the wing deformation and impact by the pilot arm-wearable haptic interface, which makes it possible to achieve human-robot interactive decision making.

Tilted fibre grating assisted surface Plasmon resonance for mechanical, biochemical and electrochemical sensingProfessor Tuan GuoInstitute of Photonics Technology, Jinan University, China

Surface Plasmon Resonance (SPR) optical fibre sensors can be used as a cost-effective and relatively simple-to-implement alternative to well established bulky prism configurations for in-situ high sensitivity biochemical and electrochemical measurements. The miniaturized size and remote operation ability offer them a multitude of opportunities for single-point sensing in hard-to-reach spaces, even possibly in vivo. Grating-assisted and polarization control are two key properties of fibre-optic SPR sensors to achieve unprecedented sensitivities and limits of detection. The biosensor configuration presented here utilizes a nano-scale metal-coated tilted fibre Bragg grating (TFBG) imprinted in a commercial single mode fibre core with no structural modifications. Such sensor provides an additional resonant mechanism of high-density narrow cladding mode spectral combs that overlap with the broader absorption of the surface Plasmon for high accuracy interrogation. In this paper, we briefly review the principle, characterization and implementation of plasmonic TFBG sensors, followed by our recent developments of plasmonic fibre-optic vector magnetometer, the “surface” and “localized” affinity studies of the biomolecules for real life problems and the electrochemical actives of electroactive biofilms for clean energy resources.

The specialty optical fibres, which take the form of cylindrical fibres, flat fibres and photonic crystal fibres with different dopant concentrations, are characterized for numerous dosimetric parameters. We report specifically two methods in characterizing the absorbed dose, namely Thermoluminescence and Radioluminescence. Results have indicated the usefulness of specialty optical fibre fabricated for specific applications ranging from environmental, diagnostics, therapy and industrial, with doses ranging from mGy to kGy.

Ultrahigh resolution fibre Bragg grating sensors for strain and temperature measurementsA/Professor Qingwen LiuState Key Laboratory of Advanced Optical Communication Systems and Networks, Shanghai Jiao Tong University, China

Fibre Bragg Grating (FBG) strain sensors are well-known for their advantages such as small size, low cost, perfect linearity over a large strain range, and the ability of multiplexed sensing. They are also very attractive for geophysical applications if they can provide the required nano-order strain resolution in quasi-static domain. This presentation reviews our recent work on ultrahigh resolution FBG sensors. This includes high sampling rate strain sensors with pε-order strain resolution by using of two feedback loops, the first demonstration of time-division-multiplexed FBG strain sensor array with sub-nano-order resolution, and the simultaneous measurements of strain and temperature using one piece of FBG with sub-micro strain resolution and mK temperature resolution. The key technologies towards ultrahigh resolutions and the implementation of FBG sensors for in-situ measurement of crustal deformation are introduced. Those ultrahigh resolution FBG sensors provide powerful tools for environmental monitoring and industrial applications.

Conveyor idler bearing wear detection using fibre optics P. WilsonMining3, Pinjara Hills, QLD, Australia

Conveyor maintenance is a significant daily problem for the mining industry. Conventional methods of detecting bearing failure in conveyor rollers are unreliable, time-consuming and labour intensive. Acoustic sensing using fibre optic cables is being developed at Mining3 and the current prototype is under test at an underground coal mine. To date, the research team has overcome the difficulties of conversion of large data files into a usable format, the pre-processing, conversion to a frequency response and post-processing filtering. The technology has been shown to be a trustworthy diagnostic tool. Current work includes the development of automatic analysis of conveyor condition.

Distributed temperature sensing to examine flow behaviour in gas drainage boreholes E. Prochon1,*, N.N. Danesh2 and S.M. Aminossadati21Mining3, Pinjara Hills, QLD, Australia2School of Mechanical and Mining Engineering, The University of Queensland, Australia

This paper presents the results of a comprehensive study on the effectiveness of deploying fibre-optic based Distributed Temperature Sensing (DTS) technology in pre-mining gas drainage boreholes. The aim is to identify the changing thermal characteristics of gas flow along the length of the borehole in order to provide a step change in the way that gas drainage is managed and reported. Current techniques used in the coal mining industry do not provide any information on where the gas flow is originated and how effective the gas drainage is throughout a large region. The results of the research demonstrate the ability of the technology to identify “signature” changes in temperature inside the borehole that could be directly associated with gas emissions, borehole blockages, as well as the presence and source of water.

Development and characterisation of an innovative FBG-based low cost shape sensor M. Amanzadeh1,*, H. Pauer2,3, R. Sit¹, W. Tuschmann³, H. Woern² and S.M. Aminossadati¹1School of Mechanical and Mining Engineering, The University of Queensland, Australia²Institute for Anthropomatics and Robotics Intelligent Process Control and Robotics Karlsruhe Institute of Technology Karlsruhe, Germany³Institute of Algebra and Geometry Karlsruhe Institute of Technology Karlsruhe, Germany

Various industrial and robotics applications require the real-time measurement of an object’s deformation and position. Fibre Optic Shape Sensing (FOSS) is the three dimensional reconstruction of an object’s shape using embedded fibre optic strain sensors. Currently established applications of FOSS, predominantly in medical robotics, require the shape reconstruction to be highly precise - thus resulting in higher costs for sensor materials, special fibres and development methods. Potential industrial and aerospace positioning applications requiring optimised accuracy incites the development of a low-cost shape sensor. This paper presents the design, development and characterisation of a low-cost shape sensor using Fibre Bragg Grating (FBG) sensors. A sensor head production procedure was developed, allowing three standard single mode fibres to be embedded within a flexible silicon tubing. A 30-centimeter-long sensor head prototype was characterised using multiple measurements of various known shapes. A multi-sensor fusion algorithm was designed and demonstrated, using the characterisation data set for calibration.

High capacity torque and compression measurements using fibre optic sensors K. Hoehn1,*, A. Olsson1 and J.W. Arkwright2

1CSIRO Mineral Resources, QCAT, Pullenvale, QLD, Australia2Flinders University at Tonsley, Australia

Deformation of objects or structures under applied loads have traditionally been measured using electrical strain gauges. Several techniques are also known for measuring strain along optical fibres, which is desirable in a range of circumstances, e.g. in systems with space constraints or where many measurement points are required. Optical fibres, however, are known for being fragile and having a low tensile strain limit. This paper presents a realisation of a high capacity, directional torque and compression sensor using a single optical fibre with multiple Fibre Bragg Gratings (FBGs). It describes the design parameters to adjust the sensing range to the expected forces and showcases an application for the mining and drilling industry.

We present a novel approach to active Q-switching of an integrated waveguide chip laser that utilizes a compact deformed helix ferroelectric liquid crystal cell. Unlike previously demonstrated methods, this device can be directly integrated onto the waveguide chip and can be controlled by low power, low voltage drivers. The technique presented in this paper enables the fabrication of a fully monolithic and compact laser source that can emit short laser pulses with high peak power levels and variable repetition rates. Our experimental results show laser pulse durations below 40 ns at repetition rates ranging from 0.1 to 20 kHz and a maximum slope efficiency of up to 22%. Numerical simulations are also presented to support the experimental results. This novel, integrated and low-cost laser source is a promising tool for a broad range of applications such as trace gas sensing, LIDAR, and nonlinear optics.

Light source based on blackbody radiation for the optical fibre sensing system in high temperature applications T. Chen, X. Lei*, W. Chen, X. Liu, Y. Qi and W. ZhangThe Key Laboratory for Optoelectronic Technology & Systems of Ministry of Education, Chongqing University, Chongqing, China High-temperature sensing or strain sensing at high temperature in harsh environments is a challenging industrial task. Optical fibre sensors, especially Fabry-Perot sensors or FBGs, have attracted much attention because of their promising characteristics, such as miniaturization, thermal stability, and a corrosion resistant nature. In an optical fibre sensing system, the broadband light sources often needed to supply energy for sensing and demodulation. While at high temperature, the blackbody radiation energy of materials is strong, so it has the great potential to become the light source of an optical fibre sensing system. In this way, the optical fibre sensing system architecture can be simplified and system cost can be reduced. In this paper, a blackbody radiation cavity model based on an aluminium tube is presented and the influence of length of black body cavity, numerical aperture of fibre, fibre core area on coupling efficiency is analysed according to the numerical aperture angle theory. Simulation and experiment results show that the length of the black body cavity has little effect on the coupling efficiency and the larger the fibre core area, the larger the numerical aperture, the higher the coupling efficiency.

Fibre optic seismometer based on π-phase-shifted FBG and swept optical SSB-SC interrogation technique W. Zhang1, W. Huang1,*, L. Li2, W. Liu3 and F.

A fibre optic seismometer based on π-phase-shifted FBG (π-FBG) is proposed. The static wavelength/strain of the π-FBG is measured by a swept optical suppressed carrier single sideband (SSBSC) interrogation technique with a reference FBG resonator. A broadband (DC-50 Hz) wavelength/strain with 0.0006 pm (0.47 nε) resolution is demonstrated. As a reasonable double-diaphragm acceleration model is realized, the seismometer works from 20 s to 50 Hz and reaches a noise level of -130 dB at 1 Hz (re: 10×log m2s-4/Hz) which meets the earth’s background noise. The proposed seismometer has the ability to record a close, small earthquake with high signal-noise ratio (SNR).

Noise-like pulses (NLPs) are of interest as they can provide low temporal coherence, smooth and broad spectra and high brightness. Owing to these merits, NLPs can facilitate many optical sensing applications, such as hybrid interrogation of high-count low reflectivity fibre Bragg grating arrays. In this paper, we report the abnormal NLP evolution in a passively Er-doped mode-locked fibre laser, of which the optical spectrum, the pulse energy and the pulse distribution in the fibre laser cavities are controllable as desired. Both the experimental results and a theoretical investigation of the dynamics of the inner pulses are presented.

We designed and fabricated a novel twin-core optical fibre with a large hole adjacent to the center core. First, the normal modified chemical vapor deposition (MCVD) technology was used to fabricate a single core fibre preform. Then, another core preform was inserted into a small hole which was pre-drilled and fused together with the initial preform. Finally, the fibre preform with a drilled large hole near the center core was drawn into a fibre. The microstructure fibre with such an air hole can be regarded as a liquid flow channel, therefore it will be a promising candidate for a compact in-fibre integrated microfluidic sensor

A novel pipeline leak detection system using Fibre Bragg Grating-based pressure sensor array J. Wang*, L. Zhao, T. Liu and Z. LiLaser Institute, Shandong Academy of Sciences, Jinan, China

In this paper, a novel design and the underpinning technical principles of a negative pressure wave (NPW)-based pipeline leak detection system are reported. The design is configured using a Fibre Bragg Grating (FBG) pressure sensor array. To evaluate this, a pipeline leakage test platform has been established and experiments have been conducted, in order to verify the performance of a system using this FBG-based approach. Experiments have been carried out to investigate the performance of the FBG-based pressure sensor, and the relationships between the pressure amplitude change at the leakage point, the leakage level and the pipeline pressure level. The results show that the FBG-based sensor has faster response time, and less measuring error than the common pressure sensors used in the traditional NPW detection system. Additionally, the novel detection system is capable of achieving a higher leak-location accuracy and is able to detect smaller leakage volumes.

Strain and temperature insensitive optical fibre grating refractive index sensor R.X. Tan*, S. Yap and S. TjinNanyang Technological University, Singapore

We propose and investigate with numerical models, an optical fibre refractive index sensor based on polarisation mode splitting by a uniform fibre Bragg grating (FBG) inscribed in standard single mode fibre side etched into D shaped at the FBG site. Orthogonal polarisation mode reflected by the FBG from an unpolarised source will split according the extent of each mode propagating out of the etched fibre side and the refractive index of the environment. This results in an environmental strain and temperature insensitive refractive index sensing instrument measured by Bragg wavelength difference of orthogonal polarisations.

This paper details a study carried out on the application of FBG sensors for investigation of delamination crack status in glass fibre reinforced composite materials. A woven glass (0/90) epoxy composite sample containing a purposely created delamination is subjected to a tensile loading whilst monitoring the FBG sensor spectra response. Additionally, the thermoelastic response was captured with an infrared camera focused on the sample to detect the delamination crack tip exactly. A finite element analysis (FEA) was performed using cohesive elements to simulate the delamination crack tip of the delamination under a monotonically increasing axial load. It is shown that the delamination crack tip inferred from thermal stress analysis (TSA) results was consistent with the FBG sensor reading. The measured delamination damage is in a reasonable agreement with FEA simulation results.

Detection of refractive index change from the critical wavelength of an etched few mode fibre C. Lu*, X. Dong and J. SuInstitute of Lightwave Technology, School of Information Science and Technology, Xiamen University, Xiamen, Fujian, China

A novel scheme for the detection of surrounding refractive index (SRI) change based on the mode interference in a special few mode fibre (FMF) is proposed in this paper. The parameters and index profile of the FMF are specifically designed so that only LP01 and LP02 modes are transmitted within the operation wavelength, and the propagation constant difference, between these two modes reaches maximum at critical wavelength (CWL). An in-line Mach-Zehnder interferometric sensor for detection of SRI is constructed by splicing FMF with two sections of single mode fibre. We demonstrated at the first time that the CWL will change monotonically with the change of SRI in the measurement range of 1.33~1.45. The detection of SRI via monitoring the shift of CWL is promising in practical applications and superior to the traditional detection method via monitoring merely peak/dip wavelength shift, since the latter usually suffers from limited measurement range and multi-value problem.

Validation of bare FBG sensors in monitoring compressive rock mass deformation H. Gong*, M. Kizil, S.M. Aminossadati and Z. ChenSchool of Mechanical and Mining Engineering, The University of Queensland, Australia

The major issues with the current roof stability monitoring system used in underground coal mines include a lack of systematic real time data recording schemes and the use of electrical sensing components that are not intrinsically safe in an underground explosive workplace. Although an advanced system based on fibre optic sensing (FOS) technologies have increasingly drawn attention from the mining industry, their applications in coal mines is still challenged by a number of factors. Those of primary concern include the survivability when subjected to large strain ranges, appropriate fibre encapsulation and installation methods as well as the need to minimise measurement errors due to the strain transfer loss. This paper presents the results of a preliminary experiment aimed at developing a fibre optic based roof stability monitoring system for underground coal mines. The initial stage looked to establish a validated strain sensing system to be used in future experiments. The accuracy of the bare FBG sensors to measure the compressive strain for rock mass is validated against the electrical strain gauges and LVDT. Using the stress-strain curve and Young’s modulus of the standard samples as a reference, the experimental results show that the bare FBG and electrical strain gauges can provide accurate and reliable compressive strain measurements for material with different mechanical properties.

Fibre optic humidity sensors for wastewater environments M. Ams¹,*, H. Bustamante², S. Clark³ and M.J. Withford¹¹MQ Photonics Research Centre, Department of Physics and Astronomy, Macquarie University, Australia²Sydney Water Corporation, New South Wales, Australia³Department of Earth and Planetary Sciences, Macquarie University, Australia

Australia waste utilities annually spend over $1.4 billion detecting, mitigating and repairing pipe failure. Wastewater pipe failure is primarily triggered by concrete corrosion. Being able to directly measure key chemicals that cause this corrosion could lead to a predictive capability to extend the life of wastewater networks. The primary interest of this paper is to create packaged fibre Bragg grating (FBG) sensors to measure humidity in wastewater environments. In particular, we outline the inscription of Type II-IR FBG sensors (without the use of a phase mask) in fibre cores using a point-by-point (PbP) technique and ultrashort laser pulses. The FBG sensors were written through the hygroscopic polyimide fibre coating which swells with an increase in moisture. This expansion can be monitored by the FBG giving a direct relative humidity reading. The fabrication and characterisation of such humidity sensors will be presented.

Mining slope stability monitoring using fibre-optic sensing B.Yang1,*, S.M. Aminosadati¹, M. Kizil¹, Z. Chen¹ and G. Kennedy²1School of Mechanical and Mining Engineering, The University of Queensland, Australia²Mining Research and Development Centre, Simtars

Slope movement is the most common ground hazard in open pit mines. Slope stability issues contribute to less than 1% of the reported accidents; they are, however, responsible for up to 15% of fatalities in surface mines. The consequences of the instability of the slope include the endangerment of lives, disturbance of mining operations, destruction of equipment, cost of recovery, essential loss of profit to the company and in extreme cases, closure of the mine. Monitoring the slope deformation is the most effective method to avoid or reduce the risk caused by unexpected slope failure. Deformation of tension cracks on the slope crest is the first signpost of slope instability. Additionally, knowledge of the shear failure plane as a result of the internal slope movement provides critical geomechanical information. Many techniques have been designed and developed to monitor such movement. However, the technologies have several drawbacks: intense labour required and discontinuous measurement on the inclinometer; significant wiring effort and power supply required for large area monitoring by extensometer. A multi-location slop movement monitoring system that is able to be automated, work in real time and remain cost efficient is desired by the surface mining industry. The nature of a fibre optic sensing system provides real-time remote monitoring, it is intrinsically safe, has a low energy requirement and can be used for multi-points sensing of up to one thousand points with one unit. Fibre optic based sensing system can help to assess the stability of the slope, provides an early indication of slope instability and predicts the time of failure. This paper reviews the current development of fibre-optic sensing in slope stability monitoring.

Some novel doping diamagnetic silica optical fibres, such as PbS, EuF3, and Pb-doped optical fibres are fabricated by atomic layer deposition (ALD) doping technique combined with conventional modified chemical vapor deposition (MCVD) process. For the PbS-doped fibre and EuF3-doped optical fibre, their Verdet constants are higher than that of a single model fibre (SMF) at different wavelengths (660, 808, 985, 1310, and 1550 nm). Especially, the Verdet constant of PbS-doped optical fibre, EuF3-doped optical fibre, Pb-doped optical fibre and SMF are 0.6596, -0.978, 0.6309, 0.5780 rad T-1m-1, respectively. The Verdet constant of PbS-doped optical fibre, EuF3-doped optical fibre and Pb-doped optical fibre are 14%, 69% and 9% larger than that of SMF at 1550 nm, respectively.

Micro-seismic monitoring of micro cracking of rock or rock mass is important for assessing the rock mass integrity and to take necessary precautions in the stability analysis of underground and open pit geomechanical structures. Precursors to major failure and micro-mechanics of deformation of rock can be best understood in the laboratory under controlled stress conditions. An experimental program was envisaged to understand the cracking activity during loading of a rock specimen both in compression and in tension. For monitoring tensile stress assisted cracking activity, the Brazilian tensile strength test configuration was adopted and for the compressive stress assisted cracking, a uni-axial compressive test configuration was considered. Using fibre Bragg gratings (FBGs), acoustic emission (AE) monitoring was carried out with FBG sensors embedded to the rock samples for both test configurations. The FBG sensors picked up the cracking activities and the failure points coinciding with load drops on the stress-strain diagrams. FBGs could be used as an alternative to PZT/geophone sensors and could be effectively deployed in underground mines quite safely without encountering any power related hazards.

Optical fibre sensors based safety monitoring system for iron mine gob area and underground grouting curtains Z. Sun¹*, L. Jiang², G. Song², B. Hu², J. Qi³, L. Zhang³, H. Wang³ and T.

The ground pressure and ground subsidence are all the result of displacement of overlying rock mass in the mined-out area after the ore body is mined. This paper presents the details of the monitoring and early-warning system of mine rock mass activity based on optical fiber micro-seismic and dissociation sensor network. The project was carried out in Laiwu Gujiatai iron mine grouting curtain body and Zhaozhuang iron mine mined-out area. The on-line monitoring of the rock mass movement and the safety status of the grouting curtain body was carried out. The micro-seismic activity and rock displacement of the overlying rock and the underground grouting curtain were monitored based on real-time and on-line monitoring, analysis of the stress field changes in the production process, real-time monitoring of goaf overlying rocks and grouting curtain body stability, surface subsidence, water inrush and other dynamic disasters forecast. The project provides a theoretical basis and practical guidance for the long-term monitoring and early warning of ground subsidence and underground water inrush.

Wide-range Fibre Bragg Grating displacement sensor with temperature compensation Y. Zhang, Y. Tian, X. Fu and W. Bi*School of Information Science and Engineering, The Key Laboratory for Special Fibre and Fibre Sensor of Hebei Province, Yanshan University, Qinhuangdao, Hebei Province, China

A novel Fibre Bragg Grating (FBG) displacement sensor based on the cantilever beam structure is designed in this paper. Two fibre gratings with different central wavelengths are symmetrically pasted on to both sides of the cantilever beam. When the free end of the cantilever beam is changed, the two fibre gratings are respectively subjected to tension and pressure, which lead to the drift of the gratings’ center wavelength in the opposite direction. At the same time, the problem of cross sensitivity between temperature and displacement is solved. In addition, a smart device used to change the measuring range of the sensor is designed and it is also easy to assemble and disassemble, so the whole sensor can be widely used. The experimental results show that when the range is 30mm, the average sensitivity of the displacement sensor is 92.4pm/mm and the correlation coefficient is 0.999. While the range is 60mm, the average sensitivity of the displacement sensor is 47.7pm/mm and the correlation coefficient is 0.998.

Predictive network modelling with live sensor data C. Stewart1,2,*, S.M. Aminossadati1 and M. Kizil11School of Mechanical and Mining Engineering, The University of Queensland, St Lucia, QLD, Australia2Chasm Consulting, Brisbane, Australia

Advanced fibre-optic based sensing systems are fast growing and replacing conventional sensors in many industries due to their reliable measurements, fast response, and intrinsically safe operations. The deployment of any sensor system however, remains a potentially expensive and disruptive activity, and may be limited in areas with difficult or unsafe access, or without communication systems. A predictive modelling tool that accepts live data and outputs both real and predictive estimations between sensors may have great application by limiting the number of sensors required, or covering areas unable to be monitored by sensors. A transient based simulation model incorporating real time actual and simulated data can be merged to display predicted conditions through a mine or tunnelling system at any time. While downstream data can be predicted with some confidence, a method of predicting upstream data where no sensors are present, as well as estimating the reliability of the data is discussed in this paper. Modelling algorithms are proposed to accommodate these concerns. “Ventsim Visual” software is used as a graphical interface to demonstrate the effectiveness of this approach.

Gas pressure sensing based on antiresonant reflecting guidance hollow-core fibre M. Hou*, Y. Wang, F. Zhu, Y. Wang and C. LiaoKey Laboratory of Optoelectronic Devices and Systems of Ministry of Education/Guangdong Province, Shenzhen University, Shenzhen, China

A gas pressure sensor based on an anti-resonant reflecting guidance mechanism in a hollow-core fibre (HCF) with an open microchannel is experimentally demonstrated. The microchannel is created on the ring cladding of the HCF by a femtosecond laser to provide an air-core pressure equivalent to the external pressure. The HCF cladding functions as an anti-resonant reflecting waveguide, which induces sharp periodic losses in its transmission spectrum. The proposed sensor is miniature, robust, and exhibits a high pressure sensitivity of 3.592 nm/MPa, a low temperature cross-sensitivity of 7.5 kPa/°C.

A humidity sensor based on etched Fibre Bragg Grating (eFBG) coated with Titanium dioxide (TiO2) nanoparticles is fabricated for real-time humidity monitoring. The simple and cost-effective dip coating method is used to coat TiO2 nanoparticles on the surface of etched FBG. The shift in Bragg wavelength (λB) is used as the probing parameter to interpret the measurement. A sensitivity of ~7.76 pm/ %RH has been achieved for the experiments carried out at 25OC in the relative humidity range of 20% to 80%. The sensitivity is enhanced to 11.01 pm/ %RH when the temperature is increased to 50OC.

Due to the coal mine safety requirements for a new generation of methane sensors in recent years, the coal mine methane laser sensor (CMMLS) has attracted more and more attention. Based on the principle of laser absorption spectroscopy, a CMMLS was developed and a series of detailed performance test were carried out. Compared with traditional catalytic combustion sensors and infrared sensors, the CMMLS has many advantages, such as a large range, high precision, low power consumption and it is calibration free. In the application of the coal mine safety monitoring, the superior performance of the CMMLS has been verified, and it has good application prospects.
