Paper Abstract

A generalization of the halftone screen process for achieving nonlinear functions in coherent optical systems is given. Using non-monotonic periodic halftone screens, functions with an arbitrary number of slope changes can be obtained in the first diffraction order. A detailed synthesis algorithm for specifying the screen shape is described, and some preliminary experimental results on real-time nonlinear processing are presented.
