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.

Abstract: A light detector is provided to include a light receiving array having a plurality of light receivers respectively outputting pulse signals upon incidence of photons. A delay setting value is set which is used to adjust a time interval from when the pulse signals are output from the light receiving array to when a response number, which is a specified number of the light receivers outputting the pulse signals, is acquired.

Abstract: A light detector is provided to include a detection module, and a monitoring SPAD. The detection module includes an SPAD that is an avalanche photodiode operable in Geiger mode; the detection module is configured to perform light detection by applying, to the SPAD, a reverse bias voltage in a reverse direction. The monitoring SPAD has characteristics identical to characteristics of the SPAD in the detection module. The reverse bias voltage is generated to be applied to the SPAD in the detection module based on (i) a reference breakdown voltage set from a breakdown voltage generated across the monitoring SPAD in Geiger mode and (ii) a predetermined excess voltage.
