The Factory Acceptance Test (FAT) results for the projection optical subsystem (POS) of US Army STIRCOM's dynamic infrared scene projector (DIRSP) are presented in this paper. DIRSP is a low background (-35 degrees Celsius) hardware-in-the- loop (HWIL), long-wave infrared (LWIR) scene projector built by Mission Research Corporation (MRC) for use by the Redstone Technical Test Center (RTTC). It has an effective emitter array size of 1632 X 672 suspended-membrane micro-resistor elements. The POS is responsible for generating this effective array size from three smaller arrays using a mosaic image combiner, adding background light from an external blackbody, and collimating the combined radiation with a 5:1 vacuum enclosed -35 degree Celsius zoom lens. The FAT results reported demonstrate good POS performance compared to the design for focal length, F/#, MTF and apparent temperature.
