Sampling and Restoration of Images Formed in Partially Coherent Light.

Abstract

In this work, the author gives a new description of the process of image formation by an optical system of a generalized partially coherent object. The imaging of a partially coherent object distribution is considered here as a process of the retransformation of the far-field coherence function due to the object. Based on this approach, the image can be shown to be built up from an incoherent superposition of a number of sinusoidal fringes of intensity. Each such sinusoidal intensity fringe, which we call a Young's interference fringe component, can be obtained from a sampling of the far-field coherence function of the object. The imaging of a partially coherent object is thus considered here from a sampling and image synthesis viewpoint.
