Paper Abstract

This paper describes recent research at Arnold Engineering Development Center to investigate aspects of using laser-based direct write scene generation photonics complementary to traditional blackbodies and thermal sources for focal-plane-array diagnostics. The equivalence of using lasers and thermal sources for photodetection and focal-plane-array evaluation depends not only on generating the same mean number of detectable photoevents, but also depends on generating the same photonic noise needed to accurately simulate photostochastic events representative of statistical ensembles and operational envelopes expected from normal focal-plane-array modes and sensor operation. Effective signal-to-noise ratios and photodetection equivalence also depend on the absence of signal artifacts or perturbations resulting from using laser-based photonics for optical diagnostics. The useful domain and relevance for using lasers complementary to thermal sources for photodetector and focal- plane-array diagnostics have been investigated to ascertain differences and similarities.
