Kedar Khare is currently an Associate Professor in the Department of Physics, Indian Institute of Technology Delhi, India. His research interests include problems in computational optical imaging. In recent years he has been actively engaged in pursuing research work on quantitative phase imaging, Fourier phase retrieval, computational microscopy, diagnostic imaging, cryo-EM imaging and structured light propagation in turbulence.
This book provides an in-depth introduction to modelling of long-range propagation of orbital angular momentum modes as well as more general structured light beams through atmospheric turbulence. It is a stand-alone reference material and is well suited to graduate students and researchers in optics and photonics.
