Abstract
A scanning system includes a light source configured to emit light as a series of one or more light pulses, a scanner configured to direct the one or more light pulses towards a remote target, and a receiver configured to detect light scattered by the remote target. The receiver includes a light detector element disposed on an ASIC that includes multiple comparators disposed in parallel with one another, and corresponding time-to-digital converters (TDCs) coupled to the comparator. Each of the comparators processes a received electrical signal from the light detector element to produce a digital edge signal when the amplitude of the received electrical signal reaches a particular threshold. A corresponding TDC outputs a time delay value associated with a time at which the received electrical signal reaches the particular threshold.
