Abstract
A photodetector includes plural detectors. Each of the plural detectors has a single photon avalanche diode (hereinafter referred to as SPAD) which responds to incidence of a photon. The plural detectors include at least a first detector and a second detector. The SPAD has a recovery time period until the SPAD reaches a next photon-responsive state, in response to the SPAD responding to the incidence of the photon. The recovery time period of the SPAD in the first detector is different from the recovery time period of the SPAD in the second detector.
