Sampling of Fresnel transforms
Anthony VanderLugt · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 1990
Domains other than the time or frequency domains arises naturally in coherently illuminated optical systems that produce Fourier transforms. We extend the well known result that N samples are sufficient to represent the information content in the object, image, and Fourier planes to include any Fresnel plane of a coherently illuminated optical system, provided that we use a specified sampling technique.
