About the Book :
This book provides an introduction to Fourier Optics in the light of new developments in the area of Computational Imaging over the last couple of decades. Imaging systems combining Fourier Optics principles and ideas on image reconstruction are increasingly showing superior imaging performance and are being used regularly in scientific research and in day-to-day imaging applications. This book is intended to provide a basic background of the exciting area of Computational Imaging to advanced undergraduate and post-graduate students in Physics, Electrical Engineering, and Mathematics who may wish to work with imaging systems in their future careers.
