Fig. 1: The typical output waveform from the C11209-110. Fig. 2: The counts of detected photons within 100μs at different light levels. In this figure the dashed line shows the expected number of detected photons in this fixed time interval. The solid lines then show the number of detected photons in the same period determined by the two photon counting methods. Abstract This paper proposes a method to detect photon counts from a commercial off-the-shelf SPAD array. Experiments show that using
