We propose to combine QmagiQ's strained layer superlattice (SLS) sensor technology with MIT Lincoln Laboratory's novel digital pixel readout integrated circuit (DROIC) to realize an advanced longwave infrared digital focal plane array (DFPA) with high quantum efficiency, dynamic range, and operating temperature. In Phase I, we developed the basic SLS DFPA and demonstrated its extraordinarily high signal-to-noise. In Phase II, we will optimize the DFPA, integrate it into a full-fledged surveillance system, and test it in the field. It's field performance will be directly compared to an identical system with a mercury cadmium telluride FPA.
