17. Any other information

I and my associates have developed Laser Applications/Holography and Optical Metrology Laboratory of Instrument Design Development Centre at Indian Institute of Technology Delhi. Majority of investigations/innovations made by me are directed towards industrial applications. We have invented laser based alignment system using circular gratings for its use in electrical power and others industries. Further, we have developed new applications of the invented system for the measurement of temperature and temperature profile of gaseous flame, and testing of collimation of laser beam. Measurement of temperature and temperature profile of gaseous flame is important to study the combustion of gaseous fuels, optimize the design of burners (domestic and industrial) and to control the pollutants in the combustion process. We have investigated and developed Talbot interferometry, digital speckle pattern interferometry (DSPI) and digital holographic interferometry (DHI) for measurement of temperature and temperature profile of gaseous flames. Also, we have demonstrated the use of Talbot interferometry, digital speckle pattern interferometry (DSPI) and digital holographic interferometry (DHI) to predict the effect of magnetic field on temperature and temperature profile and combustion process which is of immense importance to optimize the production of heat through combustion and reduce the pollutants in the combustion process. These experimental investigations confirms that the field enhanced mass transfer of paramagnetic oxygen allows control fuel combustion and flame shape. On administrative and managerial front as a Director of National Institute of Technology, Hamirpur (Himachal Pradesh), I have understood, analyzed and improved the technical education by identifying the existing weaknesses in the system. I and my associates formulated rules and regulations to improve the academic system and governance of the Institute and got them approved in Board of Governors and implemented them to steer the Institute in the desired direction of progress. My efforts made the congenial

7

environment for learning and research in the Institute. I was popular and respected Director among students, teachers, and staff. I initiated and with the help of my associates and board of governors, got approved many M. Tech. programs and also initiated Ph.D. program at NIT Hamirpur, and thus initiated a process to convert Undergraduate (UG) Institute to Post Graduate (PG)/ Research Institute.

Details, Application and Use to Society: Central Scientific Instruments Organization (CSIO), Chandigarh designed and developed an atomic absorption spectrophotometer for its use in industry. Due to non-availability of technical information, it was difficult to design a suitable burner, which can give a temperature of the order of 2000 K in its flame. To solve this problem, we developed speckle photography, speckle shearing interferometry and Talbot interferometry for measurement of temperature and temperature profile of gaseous flames coming out of the slot burner so that the slot size and other parameters of the atomic absorption spectrophotometer system can be optimized to get required temperature and its distribution. These techniques were also used to study the effect of introduction of water in the flame. The research work done was published in international journals.

The 23rd ICO General AssemblyICO welcomes a new Bureau and RIAO as a new international society member.

Santiago de Compostela, the city of pilgrims with its impressive cathedral and its famous botafumeiro, welcomed the participants to the 23rd ICO General Congress. In the words of its chair, Humberto Michinel, the conference pro-gram reflected the rich variety of phenomena to whose study we dedicate our lives and provided a glimpse into why we are so passionate about it. During the opening ceremony, special mention was made by M T Flores-Arias (scientific chair and optoelectronics section, Universidade de Santiago de Compostela) of the role and herit-age of C Gómez-Reino (co-chair in memoriam). The conference opened with a plenary lecture by Alain Aspect, winner of the 1987 ICO Prize.

In the words of the conference chair, the con-ference theme, Enlightening the Future, “pointed to the need of preparing future generations of sci-entists to take over and explore fascinating new

aspects of light and its applications”. And indeed, a highlight of the Congress was provided by the plenary lectures given by the recipients of the Ernst Abbe and IUPAP Young Scientist prizes, Tobias Kippenberg (2013) and Nicholas Fang (2011), and by two awardees of the IUPAP Young Scientist Prize in Optics, Andrea Alú (2013) and Göery Genty (2011). For the first time, students attending the conference organized their own parallel activities and invited the ICO president, Duncan T Moore, to discuss with them ways in which they could integrate better with ICO’s work and also participate actively in the celebra-tion of the International Year of Light 2015.

The General Assembly was attended by 64 official delegates from 33 ICO Territories and its six international member societies, along with a large number of observers. The General Assembly approved the proposed amendment to Article 1 of the ICO Statutes in order to include the word “photonics”, as transcribed in the ICO Newsletter, July 2014; the admission of the Iberian American Network of Optics (RIAO) as an international society member of ICO with the right to appoint a vice-president to the ICO Bureau; the Bureau proposal for updated Territorial Committees fees with a phasing timeline; a budget for the ICO Bureau to invest wisely in the celebration of the International Year of Light 2015; the proposal by Japan to celebrate the 24th ICO General Con-gress in Yokohama, Japan, 3–8 September 2017. The General Assembly also elected the members to the ICO Bureau 2014–2017 (see table opposite).

Participants at the conference had the oppor-tunity to interact in many social activities held during the conference, including receptions hosted by the authorities of Santiago de Com-postela and by SPIE and OSA. A tour of the region ended with an unforgettable concert of Galician Pipers at a castle in Vigo, the town of Humberto Michinel.

ICO Ne w s l e t t e rNo. 101 o c t o b e r 2014

The ICO Prize Committee, consisting of Rob-erta Ramponi (chair), Yasuhiko Arakawa, Zohra Ben-Lakhdar, Yujie Ding, Fernando Mendoza Santoyo, Maria J Yzuel, and Bingkun Zhou, awarded the 2014 ICO Prize to Prof. Martin Booth, University of Oxford, UK, “for his inno-vative and pioneering research on dynamic opti-cal methods and new approaches to adaptive optics”.

Prof. Booth leads the Dynamic Optics and Photonics Group at the University of Oxford, UK. He has over 17 years of experience in research on optical and photonic engineering, specifically in the areas of active and adaptive optics for microscopy and photonic engineering. His research group is based jointly in the Depart-ment of Engineering Science and the Centre for Neural Circuits and Behaviour in Oxford.

Prof. Booth’s research primarily concerns the development of dynamic optical methods for a range of interdisciplinary applications. A major application is the use of adaptive optics for aber-ration correction in high-resolution microscopy. This technique, originally developed for astro-nomical telescopes, uses adaptive elements, such as deformable mirrors, to correct aberrations introduced by microscope specimens. Spatial variations in refractive index due to the struc-ture of a specimen introduce aberrations that reduce the resolution and contrast of microscope images. Prof. Booth’s research has involved the development of new methods of phase meas-urement, wavefront sensing, and aberration control. This work has led to advances in bio-medical imaging, including adaptive aberration correction in confocal, multi-photon and wide-field sectioning microscopy. By overcoming the effects of specimen induced aberrations, adap-tive optical microscopes operate effectively in thick tissue specimens, where imaging capabili-ties were previously limited.

Recent research in collaboration with Yale University and the University of Cambridge has involved the development of adaptive compen-sation of aberrations for super-resolution micro-scopes. Specifically, Prof. Booth’s group has introduced the first feedback correction of speci-men-induced aberrations in stimulated emission

depletion (STED) and single-molecule switch-ing microscopes. This research is showing how adaptive optics can transform these microscopes from tools for imaging cells to effective methods for microscopy of thick tissue specimens.

His group has also made advances in dynamic optics for sub-micrometer scale laser fabrication systems. In the focusing of laser light inside transparent materials, spherical aberration is caused by refraction at the surface. Adaptive aberration correction overcomes this problem and enables diffraction limited focusing at depth. This technique is key to obtaining preci-sion three-dimensional fabrication throughout the volume of materials. Further advances have been made in the dynamic parallelization of laser fabrication through holographic, refractive, and hybrid methods. These methods permit the control of hundreds or thousands of laser foci in parallel, increasing the speed of fabrication systems. Applications of these technologies have included photonic crystals, waveguide circuits for quantum optics, and diamond photonics.

Prof. Booth’s research career started in 1997 when he was a visiting student in the group of Prof. Stefan Hell at the Max Planck Institute of Biophysical Chemistry in Göttingen, Germany, where he worked on continuous-wave two-photon microscopy. His doctorate, obtained from the University of Oxford in 2001 and supervised by Prof. Tony Wilson, concerned the development of the first adaptive optical confocal microscope. In the same year, he was appointed a Junior Research Fellow at Christ Church, University of Oxford. From 2003–2008 he was a Royal Academy of Engineering/EPSRC Research Fellow, follow-ing which he was an EPSRC Advanced Research Fellow until 2013. He was then appointed to a Senior Research Fellowship before becoming Pro-fessor of Engineering Science in 2014. In 2012, he was awarded the “Young Researcher Award in Optical Technologies” from the Erlangen School of Advanced Optical Technologies at the Univer-sity of Erlangen-Nürnberg, Germany, alongside a visiting professorship at the university. He is also co-founder and director of Aurox Ltd, a univer-sity spin-off company, and is a fellow of Jesus Col-lege, Oxford, UK.

ICO Ne w s l e t t e r No. 101 o c t o b e r 2014

The ICO Galileo Galilei Award Committee, consisting of professors Zhou Bingkun (chair), G Von Bally, P K Buah-Bassuah, Y Ding, Min Gu, B P Pal, T Szoplik, V I Vlad, and I Yamaguchi, awarded the Galileo Galilei Award 2014 to Prof. Chandra Shakher, from the IIT Delhi, India, “For outstanding contributions to the field of holographic and speckle metrology, which were achieved under comparatively unfa-vorable circumstances”.

Chandra Shakher was born in Meerut, Uttar Pradesh, India, in December 1949. He received his MSc degree from Meerut University in 1970, his Master of Technology in applied optics from the IIT Delhi in 1976, and his PhD in physics from the Indian Institute of Technology Madras in 1980. A unique aspect of Prof. Shakher as an Indian professor is that he has the experience of working for both Indian industries and aca-demia, and has led and promoted research and education of optical metrology by establish-ing a bridge between industries and academia in India. He served as scientist at Central Sci-entific Instruments Organization, Chandigarh, from November 1979 to May 1983. In May 1983, he joined Bharat Heavy Electricals Limited (BHEL), Corporate Research and Development Division, Hyderabad, as deputy manager. In March 1989, he joined the Instrument Design Development Centre (IDDC) of the IIT Delhi as Chief Design Engineer and subsequently was promoted to the position of professor in 1995.

He was director, National Institute of Technol-ogy, Hamirpur (Himachal Pradesh), India dur-ing 2002–2004. Currently, he is professor at the Instrument Design Development Centre, IIT Delhi, and he was a member of the Technology Business Incubation Centre in helping young scientists with the establishment of their own business.

The focus of his group has been on problems of practical engineering in non-destructive test-ing. Especially noteworthy is his work on the application of speckle shearing, Talbot, and Lau phase interferometry for the measurement of temperature and temperature profile of gaseous flames for combustion analysis.

He and his team have also developed a Dig-ital Speckle Pattern Interferometry (DSPI) sys-tem with wavelet filtering for the measuring/monitoring of vibration of plates, outer casings of electric motors, computer hard discs and tweeters of music systems. The system is also used for the measurement of Young’s modulus of materials using plate vibrations. He has also designed and developed a DSPI system for the measurement of temperature of large size flames (20 cm × 20 cm).

Prof. Shakher’s awards and honors include: Fel-lowships of SPIE, and Indian National Academy of Engineering, the National Research Develop-ment Corporation Independence Day Award 1993, and a member of the editorial board of Optics and Lasers in Engineering (Elsevier).

The ICO Galileo Galilei Award 2014 The award goes to Chandra Shakher, IIT Delhi, India, a leading researcher bridging academic research and industrial applications in India.

ICO mourns the passing of Roberto Ortega (1946–2014)A remarkable promoter of optics in Mexico.

Prof. Roberto Ortega Martínez was born in Mexico City. He obtained his BSc (physics) from the Universidad Nacional Autónoma de México (UNAM) where he began teaching even before he graduated. While at the UNAM, he was among the outstanding and enthusiastic students that took part in the social demonstra-tions of 1968 in Mexico.

His BSc dissertation, presented in 1971, included the design and construction of very low electronic noise amplifiers that were used for over a decade in the San Pedro Mártir based Observatorio Astronómico Nacional of the UNAM, OAN-SPM, in Mexico. He also col-laborated with the installation of the control instrumentation, the photometric detection systems, and the physical infrastructure of the OAN-SMP 0.84 m and 1.5 m astronomical telescopes. After one and a half years at the Optical Sciences Center of the University of Arizona, OSC-UA, he joined the Facultad de Ciencias of the UNAM, FC-UNAM as instruc-tor, and became FC-UNAM faculty in 1976. He obtained his MSc and PhD degrees from

the UNAM in 1976 and 1986, respectively. He also worked as associated senior researcher of the Instituto de Astronomía of the UNAM, IA-UNAM, from 1975–1982, where he participated in projects on stellar spectrometry, Michelson-Fourier interferometry, and in the electro-mechanical instrumentation installation and maintenance of several astronomical telescopes of the San Pedro Mártir and the Tonantzintla observatories.

In 1983, Prof. Héctor Domínguez, then gen-eral director of the former Centro de Instru-mentos of the UNAM, CI-UNAM, (currently known as the Centro de Ciencias Aplicadas y Desarrollo Tecnológico of the UNAM, CCA-DET-UNAM), invited Prof. Ortega to estab-lish an applied optics laboratory, a remarkable effort-consuming project if we consider the small number of optics scientists available at the UNAM in the 1971–1981 decade (a signifi-cant number of optics scientists left the UNAM in 1971 to establish the Instituto Nacional de Astrofísica, Óptica y Electrónica, INAOE, in Tonatzintla, and later in 1980, the Centro

In response to these conditions, Prof. Ortega immediately recruited several recognized inde-pendent researchers, and in 1984 he established the Laboratorio de Óptica Aplicada of the CI-UNAM (which later became the Departa-mento de Óptica y Microondas of CCADET).

At the CI-UNAM (and later CCADET-UNAM), Prof. Ortega developed several optical instruments and laser applications in the area of medicine for public hospitals and guided his students to develop laser spectrometers for non-linear optics research and laser applications to medicine (cardiology, odontology, opthtalmol-ogy and oncology). In 1995 he rose to the senior researcher level of the UNAM, and was granted the PRIDE D distinction, and became a mem-ber of the Sistema Nacional de Investigadores (SNI), where he reached the second highest level in 1998. In 1996 he secured funding from the UNAM and established the first Laboratorio de Óptica de Pulsos Ultracortos in Latin America,

to carry out research projects in photonics, non- linear optics, and ultra-fast optical phenom-ena, and devoted his research to the study of the optical self-correlation techniques used for ultra-short pulses characterization, as well as the FROG technique and associated Wigner func-tion modelling. In 2006 he established the Labo-ratorio de Óptica no Lineal of CCADET. All of the laboratories established by Prof. Ortega are currently recognized as among the most impor-tant in Mexico.

Prof. Ortega strongly believed that optics was an illustrative field for young scientists and also that a piece of general culture needed to be appreciated by students at all educational levels. He was a remarkable promoter of optics in Mex-ico, committed to scientific and technological development. The Mexican optics and photonics community mourns his passing and expresses its condolences to his mother and friends in numer-ous solidarity messages. RIP.Dr Martha Rosete, CCADET, UNAM

SCIENCE & TECHNOLOGY

Engineering

Lasers add zing to alignment systemsIndian engineers have developed a high-precision, laser-based alignment system essential

for installing sophisticated machinery and ensuring its optimum functioning.

A symmetrical moire pattern indicates perfect alignment (left),while any misalignment results in an asymmetrical pattern.

37

Unique facility

For instance, he explains, if thetwo objects to be aligned are placed5 m apart. the instrument can detecta deviation of as little as 0.005 mm,while imported machines cannot

detect deviations of lessthan 0.025 mm.

But Chandrashekhar's system cannotalign objects placedmore than 10 m apart.The long-distance aligning accuracy is limitedby the tendency of thelaser beam to swerve.The narrower the beam,the more it wanders asdistance increases.Imported machines usenarrow beams that canalign objects upto a distance of 15 m, but theycannot detect a misalignment of less than0.25 mm at this distance. "We have used awider beam - with a

diameter of 30 mm - and hope toextend the range by another 20 m,while maintaining higher accuracy,"Chandrashekhar explains.

Besides, the indigenous device has aunique facility not offered byany other alignment system - itenables the operator to align threeobjects simultaneously. With somemodifications, the instrument caneven be L1sed to measure temperature. For example, if a burner isplaced between the two grids, thesurrounding air is differentially heated, affecting the diffraction of lightand resulting in characteristic moir~

pattern depending upon the temperature.

BHEL intends to manufacture theunits on a large scale and sell them tovarious industries. Says P V Bhat atBHEL's corporate R&D outfit inHyderabad, "The technology is readyfor commercialisation and one system is already in operation at ourHardwar unit." •

Institute of Technology in NewDelhi, who developed the systemalong with U M Chaudhari, an engineer with Bharat Heavy ElectricalsLtd (BHEL).

But two key components of thesystem - a helium-neon laser and atelescopic lens - will still have to beimported at a cost of about Rs 40,000.

The system, developed at BHEL'scorporate research and developmentunit in Hyderabad, was recently chosen for the National ResearchDevelopment Council award. Thedevice uses a laser beam and gridsthat are placed on the objects to bealigned. The laser beam passesthrough one symmetrical circulargrid, producing a corresponding symmetrical pattern. This pattern falls onthe other similar sensory grid. If thetwo object are aligned, a symmetrical pattern known as a moire patternis formed. If they are not aligned, adistorted moire pattern forms, whichcan easily be detected by the nakedeye. The degree of misalignment canthen be measured using a micrometer.

"Even without the sophisticatedelectronics used by other systems,this device is more sensitive thanimported machines up to a certaindistance," says Chandrashekhar.

WHILE constructing a wall. masonsuse a plumb-line to ensure the bricksare aligned vertically, for otherwise,the wall could fall. Butconventional methods ofalignment using instruments such as spirit-levels and plumb-lines aretime-consuming anderror-prone. They alsocannot meet the level ofprecision required toalign linear particle accelerators, aircraft wings andgenerators. so as to keepvibrations to a minimumand ensure their optimumfunctioning. Presently,laser-based alignmentinstruments are beingimported. But now,Indian engineers havedeveloped a sophisticatedalignment system thatuses lasers.

"Our system is much cheaperthan those being imported. While theimported apparatus costs us a littlemore than Rs 25 lakh, we can produce five of our own with the same
