RESEARCH EXPERIENCE

PROJECT: Complete intrinsic coincident polarimetry using stacked organic photovoltaics

ADVISOR: Dr. Michael W. Kudenov

DESCRIPTION: A theoretical model, calibration procedure, and experimental validation of an intrinsic coincident

polarimeter was demonstrated. It was proved that the use of semi-transparent, polarization sensitive organic

photovoltaics (OPVs) leveraged the advantages of the stacked photo-detector approach, and the polarimeter’s ability

to acquire responses of each OPV simultaneously, ensured high spatial and temporal resolution, which are the

primary constraints in state of the art polarimeters.

PROJECT: Snapshot Imaging Fraunhofer Line Discriminator for Detection of Plant Fluorescence

ADVISOR: Dr. Michael W. Kudenov

DESCRIPTION: A novel approach to quantitatively measure plant fluorescence was developed, based on a

snapshot imaging Fraunhofer line discriminator (SIFOLD). For the first time, the advantage of snapshot imaging

for high throughput Fraunhofer Line Discrimination (FLD) is cultivated by our system, which is based on a multiple-

image Fourier transform spectrometer and a spatial heterodyne interferometer (SHI). The theoretical model of the

SIFOLD was designed and the system was calibrated and is en route for outdoor testing.

PROJECT: Fabrication of Anisotropic Materials for Thermal Infrared based on Volumetric Periodic Nanogratings

ADVISOR: Dr. Michael W. Kudenov

DESCRIPTION: The objective of this project was to investigate a novel approach to fabricate birefringent crystals

for the thermal infrared region (7-14 µm). The technique was based on volumetric inscription of periodic sub-

wavelength structures (nanogratings), in the volume of certain transparent materials e.g. chalcogenide glass, arsenic

sulphide etc. The nanogratings are formed in the bulk of a material upon illumination with a focused and pulsed

laser beam. With the help of this technique, it is possible explore new thermal infrared measurement techniques

such as high resolution, cost efficient, imaging at these wavelengths.

ACADEMIC PROJECTS

PROJECT: Design and Calibrate a simple Stokes Imaging Polarimeter

COURSE: Polarization and Polarimetry

DESCRIPTION: The aim of the project was to develop and calibrate a simple Stokes imaging polarimeter. Data

from two scenes were collected, one indoor and the other outdoor. A DSLR camera was used for imaging purposes.

The data was collected using different polarization analyzer configurations. Using MATLAB, this data was reduced,

and the calibrated Stokes parameters were calculated.

PROJECT: Optical System Design for an Air-based Ground Imaging Platform

COURSE: Geometrical Optics

DESCRIPTION: For this project, it was required to design an optical system (using Code V), which would be

used to image the ground from an aircraft. The design had to account for several realistic design constraints, and

also well-defined requirement specifications. The parameters used were that of a more conventional and easily

accessible aircraft from Cessna: the Skyhawk.

PROJECT: Fabrication of Silicon diodes and Solar Cells

COURSE: Integrated Circuits Technology and Fabrication

DESCRIPTION: The goal of the project was to fabricate conventional silicon diodes and solar cells of different

sizes. The experiments were intended to focus on various doping and diffusion techniques. We used two different

doping methods: ion-implantation and gas phase doping in a furnace using boron doped disks. After completion of

the fabrication process, we were trained to characterize the devices using a semiconductor parameter analyzer.

PROJECT: Develop a Histogram Equalization Unit for Image Processing

COURSE: ASIC Design

DESCRIPTION: We processed a series of small (640 x 480 pixel) images to achieve histogram equalization for

each of them. The images contained 32-bit unsigned pixels representing gray scale images. It was required to design

a unit that maximized the number of images that could be processed per unit area. We thus needed to record how

long (in seconds) it took to process an image, and specify the cell area of the designed chip.
