Abstract
A single photon counting sensor array includes one or more emitters configured to emit a plurality of pulses of energy, and a detector array comprising a plurality of pixels. Each pixel includes one or more detectors, a plurality of which are configured to receive reflected pulses of energy that were emitted by the one or more emitters. A mask material is positioned to cover some but not all of the detectors of the plurality of pixels to yield blocked pixels and unblocked pixels so that each blocked pixel is prevented from detecting the reflected pulses of energy and therefore only detects intrinsic noise.
