Abstract

A computer interfaced, 5000 X 7500 picture element, 20,000 X 30,000 addressable position, spatial light modulator (SLM) system for ultra high resolution optical processing applications is described. The system consists of a host computer such as an IBM PC, electronics and optics with beam position feedback to rapidly and precisely scan a focussed laser beam over the writing area of the SLM, and an erasable, editable, SLM with nonvolatile storage of the image written by the scan system. Because the image is stored by the SLM, no periodic electronic refresh is required. The resolution and information content achieved by this SLM system is higher than that of professional quality color film. Potential applications include optical correlation, optical processing of photographic quality information, electronic holography and optical computing.
