Abstract

Opto-electronic feedback systems that consist of electrically addressed high-resolution phase spatial light modulators and large-scale arrays of opto-electronic feedback circuits are analyzed. Experiments were performed with a liquid crystal television panel used as a high- resolution phase modulator, and a CCD camera used as a photo-array. By synthesizing various nonlinearities and using controllable spatial coupling one can design systems capable of high-resolution adaptive phase distortion suppression and the formation of self-organized arrays of localized laser beam structures. High-resolution phase arrays are also used here for opto-electronic image edge detection.
