About SPIE @ IIST this year:
This year our concentration was more towards learning the research trends in
holography applications. Outreach activities were conducted at nearby
undergraduate colleges highlighting International Year of Light and research
opportunities going on in IIST adaptive optics lab. This led to increased
collaborations and team work. Having conducted outreach activities at 3
colleges, we have got our outreach routine for demonstrations ready and are
ready to demonstrate the same to other colleges.
Also undergrad members worked together to apply for Outreach grant cycle
1, although we couldn’t get selected. In this process we developed some team
spirit in planning and this is going to serve as an experience for the next
opportunity.
There were talks highlighting Nobel prize 2014 by faculties of IIST. A student
talk based on the topic related to a question that rose during discussions with
our Advisor, Dr. Rakesh Kumar Singh.
New research projects have started, some with interdisciplinary approach.
This lead to increased exchange of knowledge and ideas among different
disciplines.
Also, new M.Tech Optical Engg. students batch joined our SPIE Chapter. And
two professionals in the field of Image processing optics Mr. Rahul
Waghmare and in the field of Experimental Mechanics Mr. Digendranath
Swain have joined as members of our SPIE team this year.
Our Lab (highlight photos this year):
Following photos show few of the activities that happened this year.
Holography experiments with red and green laser
Interesting pattern formed on a screen when red and
green laser are passed through sucrose crystals due to
refraction and TIR in randomly shaped crystal structure.
Optical rotation effect demonstrated based on
selective scattering in direction perpendicular to
polarization of laser beam (diode laser provided in spie
activity kit)
Designs obtained using multiple diffraction grating with
varied orientations. Diffraction gratings (provided in
spie activity kit) can be seen on the right bottom.
Outreach Activity:
Outreach at NSS Women College, Trivandrum
Outreach at Mar Ivanios College, Trivandrum
Outreach at University College, Trivandrum
Guest Lectures
Lecture on Holography and Imaging systems by Dr. Bhargav
Das, CSIO, Chandigarh, India
”Optics research activities in Japan”, Dr. Yoko Miyamoto of "The
University of Electro-Communications", Japan
Student talk: Exploring phenomena by which colors manifest
in nature
It all started with a question on why peacock or even pigeon neck’s
feathers show glittering colors which vary in shades at different
angular directions. And the question on why butterfly wing’s colors
are lost on just handling it’s wings little carelessly with fingers. In
this talk we discussed various mechanisms by which we see colors
around us.
”Nonlinear optical PT-symmetric systems: Cavity control and
regularization of spectral singularity" Prof. S. Dutta Gupta,
School of Physics, University of Hyderabad
Butterfly image shows that actual color of pigment on the butterfly
wing is grey and beautiful color patterns are visible only when
illuminated by white light due to phenomena called “iridescence”.
Demonstration of photoelasticity
Demonstration of Flourescence: Green laser incident from right
side. Water with Dettol (for scattering), scattering laser
light without wavelength alteration. Whereas Rhodamine
solution(left) scattering fluorescent green color which
corresponds to lower energy electron de-excitation transition
in rhodamine.
Research Activities:
- Coherence and Polarization Optics
- Imaging behind the random scattering medium
- Quantitative phase contrast imaging through the random
scattering media
- Applications of Laser Speckles
- Holography
- Small Deformation Measurement using laser speckle
- Optical Communication
New R&D this year:
- Controlled synthesis of coherence and polarization using intensity
correlation and speckle holography technique by Mr Vinu R V
- An MTech project on “Single shot measurement of Jones matrix”
by Mr. Neeraj Kumar Soni
- Physical Optics: Generation of network of helical phase structure
in the partially coherent beam
- An MTech project on “3D reconstruction of shape of phase object”
by Mr. Atul Somkuwar
- Research in the field of ghost imaging by a PhD student,
Ms.Darshika Singh has started
- An optical metrology instrument for measuring small deformation
using laser speckle is in the process of development. Initial work in
this direction is started as part of B.Tech project by Mr. Sai
Krishna and we are looking forward to develop it in the near future.
- Research on “Secure communication using quantum optics” by Mr.
Ameen Yasir
Next Plans…
- This year, we saw technical expertise increasing among the
members of our SPIE chapter and also with increased alumni
members, we are looking forward to improve more professional
advices to the chapter members.
- With increased collaborations with other research teams, we are
looking forward to wide variety of research topics and knowledge
and skill sharing among the research team members.
- We have also started giving impetus to interdisciplinary work this
year. Collaboration with Nano-chemistry lab and Mechanical
engineering dept. of IIST have already started. Collaborations have
led to exchange and development of new ideas. This is expected to
give a good push to research of optics and developing new
applications at IIST.
