AB - The electron-beam-addressed membrane light modulator is a computer-controlled display device that allows the production of high-resolution, flickerless, dynamic infrared (IR) scenes. The projector consists of the membrane light modulator and an IR schlieren readout optical train. The light modulator is composed of a high-resolution scanning electron gun, a collector grid, and a special charge-transfer-plate anode onto which is bonded a highly reflective deformable membrane mirror. In a prototype device built at Optron Systems, readout of the system with a Helium-Neon laser operating at 3.39 micrometers has produced IR images with a contrast ratio of 40:1, a resolution of 100 television lines, and a membrane response time of 1 microsecond(s) . The goal of the next-generation device is 256 X 256 resolution elements, 100 Hz frame rate and a contrast ratio of > 100:1. We will describe the operating principles of the device, its performance characteristics, and its applications.
