Dhruvam Pandey

RESEARCH SCHOLAR AT IIT Kanpur, INDIA

I am pursuing my PhD under Prime Minister's Research Fellows (PMRF) scheme from the Department of Electrical Engineering (Photonics) at Indian Institute of Technology Kanpur. I work with Prof. G Rajshekhar in the domain of optical coherent imaging. Here, we are mainly interested in quantitatively measuring the phase of the optical wave-field scattered from an object or specimen. We work on both the experimental and computational aspects of coherent imaging. The applications of the domain includes Non-destructive Precision Metrology, Nanoscale Topography, 3D Shape Detection and Cell Imaging.
