ABSTRACT:
A photo detector matrix may have a plurality of photo detectors arranged in a matrix each generating an output signal, and a plurality of wires coupled with the photo detectors, wherein a number of wires is less than a number of photo detectors and the plurality of photo detectors are assigned to the plurality of wires such that signals generated by the plurality of photo detectors encode a location of a light peak applied to the photo detector matrix.
