Abstract:
1. An array comprising a plurality of light-sensing modules, each light-sensinglight-sensing module spaced apart from one another, wherein each light-sensinglight-sensing module has a field-of-view overlapping a portion of a field-of-view of at least one other light-sensing module of the plurality of light-sensing modules and wherein each light-sensing module comprises: an optical element adapted to direct incident light to a detector array; wherein the detector array is adapted to receive directed incident light and convert received light to a set of electrical pulses via a plurality of photodetectors, each photodetector operatively coupled to an amplifier and a threshold circuit, wherein each threshold circuit is adapted to output a detection signal to a first memory cell of a first memory store; wherein the first memory store is adapted to associate the detection signal with a time tag; and wherein the array further comprises a processing module adapted to correlate a first stored detection signal and an associated first time tag from a first light-sensing module of the plurality of light-sensing modules with a second stored detection signal and an associated second time tag from a second light-sensing module of the plurality of light-sensing modules.
