Control of a Programmable Target Simulation System for AEDC Aerospace Chambers

摘要

Simualtion of targets under 20K, 10~(-7) Torr conditions is provided in AEDC Aerospace Chambers 7V and 10V using a programmable IR scene projector. This solid-state device, known as the CRISP (Cryovacuum Resistor Array Infrared Scene Projector) generates dynamic patterns of 1 to 400 independent targets using an array of 512 by 512 emitters. Each emitter is individually programmable over a temperature range of 200 to 400 K controlled within 1 K with a 10 hertz update rate. Operation and control of this device is accomplished using a distributed system incorporating PCs, UNIX workstations, and custom electronics.
