Reusable optical image storage and processing device.

The PROM (Pockels Readout Optical Modulator) described in this paper is a device for storing and processing optical images and information in recyclable, real time operating systems. The device consists of a single active layer of a cubic photosensitive, electrooptic material. ZnS, ZnSe, and Bi(12)SiO(20) devices have been fabricated and characterized demonstrating high writein sensitivity, high resolution, high contrast, high optical and diffraction efficiency, fast recycling times, long storage times, and freedom from fatigue. Operating modes and measured performance parameters are discussed.
