Paper Abstract

Incoherent optical processing may be anal-yzed by use of the cross-spectral density function, which gives the coherence as a function of wavelength. The cross-spectral density function may be propagated through a general optical system to yield the intensity in the final plane. Analysis of a specific optical processing system shows the effects of component placement, lens aberrations, and illumination bandwidth. In particular, the use of a grating in the input plane introduces a coherence function that allows the optical processing function to take place. Through this key, we may tie together a method of optical processing, a method of image subtraction, and the Lau Effect.
