A Transportable Direct Write Scene Generation (TDWSG) test capability has been developed at the Arnold Engineering Development Center (AEDC) for visible and IR focal plane array (FPA) testing which utilizes laser sources and two-axis acousto-optic deflectors. The objective of this effort is to provide a test and evaluation facility which will help reduce space sensor development risks by testing FPAs with their data subsystems against realistic mission scenarios in a space environment. The TDWSG's performance envelope covers both high- speed (100 microsecond(s) frame time) scanning and slower staring formats. A modular concept is used to address large (512 X 512 pixel) FPAs. Scene inputs can be derived from various sources including the Strategic Scene Generation Model (SSGM). A continuance of this effort is being applied toward development of a fixed-site Scene Generation Test Capability (SGTC).
