Paper Abstract

In this paper we describe the design and performance of EHP arrays constructed at British Aerospace (BAe) for the purpose of dynamic infrared scene generation. True black body unpolarised infrared radiation is achieved by the individual control of resistor elements from an electronic backplane. Applications designed for to date have demanded a temperature range of 20 or 30°C, although the material limitations permit designs upto 400°C. Designed and achieved time constants in the millisecond range have been obtained, allowing demonstration of real time picture generation in hardware in the loop simulation systems. Videotapes of real time image generation at 100 x 100 will be shown.
