A real-time optical data processing device

Abstract

The design, operation, and structure of the hybrid field effect light valve, a real-time input device for application to coherent optical data processing (CODP), is described. The device consists of a sandwich of thin films that electrically control the optical birefringence of a thin (2 micrometer) liquid crystal layer. It has high resolution (greater than 100 1/mm), contrast ratio (greater than 100:1), speed (10 sec on, 15 sec off) and input sensitivity (about 0.3 ergs/sq cm) in addition to cost and size advantages. Performance data for a laboratory model are presented.
