Lensless imaging & microscopy using diffusers

Abstract

Computational imaging is technique which relies on reconstructing images from indirect measurements. With the advent of high performance computers, lensless computational imaging has emerged as a viable alternative to traditional lens based imaging. Particu- larly its advantages in solving some of the problems with lenses like high cost, resolution limits, aberrations,etc are lucrative. In this thesis, I discuss about lensless imaging using diffusers and finally present a simple way to improve the resolution of the system.
