1. A sensing system, comprising:
a focal plane array having an n×m array of detectors, wherein n and m are array element index values, and a single output pixel, wherein the focal plane array comprises part of a readout integrated circuit package;
a detector dual-input circuit configured to combine outputs from the detectors received at a first input channel without outputs from the detectors received at a second input channel;
a detector selector circuit establishing a first signal path between the detectors and the first input channel and a second signal path between the detectors and the second input channel, the detector selector circuit including an electronic mask forming a part of the focal plane array in the pixel and configured to map the detectors to one or both of a first detector group (Group A) and second detector group (Group B); and
a select module configured to control the electronic mask so as to connect one or more of the detectors to the first signal path to establish the first detector group and to connect one or more of the detectors to the second signal path to establish the second detector group, wherein the select module connects the one or more of the detectors to the first and second signal paths to establish the first and second detector groups based on the electronic mask.
