Avalanche photodiodes and quenching circuits for single-photon detection.

Avalanche photodiodes, which operate above the breakdown voltage in Geiger mode connected with avalanche-quenching circuits, can be used to detect single photons and are therefore called singlephoton…

Photon-efficient imaging with a single-photon camera

An array-specific algorithm is developed that converts coarsely time-binned photon detections to highly accurate scene depth and reflectivity by exploiting both the transverse smoothness and longitudinal sparsity of natural scenes and uniquely achieves high photon efficiency in a relatively short acquisition time.
