Abstract
The application of infrared scene projection systems in the cryovacuum ground-test environment is a very challenging process. Work performed at Arnold Engineering Development Center (AEDC) in the past few years can offer lessons learned from its experience in projection technologies, optical system design, optical material characteristics and measurement (including cryodeposition), positioning systems, and pertinent analytical tools involved in performing ground testing of a sensor system under flight conditions. Such testing is fundamental to characterizing its performance, and should be accomplished early and often in order to manage operational uncertainty and reduce system life-cycle cost. AEDC provides a comprehensive capability that strives to ensure system performance evaluations that are not limited by test infrastructure. For over 30 years, the space chambers at AEDC have performed space sensor characterization, calibration, and mission simulation testing on space-based, interceptor, and airborne sensors. This paper describes recent efforts at AEDC to enhance this cryovacuum test capability.
