Abstract:
A system for image acquisition with reduced noise using SPADs is configured to perform a plurality of sequential exposure and readout operations. Each exposure and readout operation includes (i) applying a set of shutter operations to configure each SPAD pixel of the SPAD array to enable photon detection, and (ii) for each SPAD pixel of the SPAD array, reading out a number of photons detected during the set of shutter operations. The system is also configured to generate an image based on the number of photons detected for each SPAD pixel during each of the plurality of sequential exposure and readout operations.
