Abstract: A combined scanning and staring (SCARING) focal plane array (FPA) imaging system having a plurality of modes of operation is provided. In one example, the SCARING FPA system includes a photodetector array with a plurality of photodetectors arranged in a plurality of photodetector rows, a readout integrated circuit (ROIC) coupled to the photodetector array, and a processor coupled to the ROIC. The processor coupled to the ROIC is configured to dynamically configure the SCARING FPA between a scanning mode of operation and a staring mode of operation.
