Abstract
A photon-counting Geiger-mode avalanche photodiode intensity imaging array includes an array of pixels (), each having an avalanche photodiode (). A pixel senses an avalanche event and stores, in response to the sensed avalanche event, a single bit digital value therein. An array of accumulators () are provided such that each accumulator is associated with a pixel. A row decoder circuit () addresses a pixel row within the array of pixels. A bit sensing circuit () converts a precharged capacitance into a digital value during read operations.
