Update on BAe resistor array design and development

We describe the status of various aspects of BAe resistor array infra-red scene projector systems for hardware-in-the- loop testing. The aspects covered include subsystem development on current 512 X 512 systems; electronic data handling and driver systems, optical projection collimators, heatsink, cooling and environmental gas control systems. Design aspects are sketched for the progression from existing demonstrator arrays of up to 1024 X 1024 into complete systems.© (1999) COPYRIGHT SPIE--The International Society for Optical Engineering.
