Document Type and Number:
Japanese Patent JP6932223
Kind Code:
B2
Abstract:
A first SPAD array on which at least one first light beam that is at least one pulse light beam is incident and which is operated in Geiger mode, a second SPAD array on which at least one second light beam resulting from the at least one first light beam reflected by a detection object is incident and which is operated in Geiger mode, a voltage generation unit that applies a reverse bias voltage to the first SPAD array and the second SPAD array, and a SPAD photon detection rate controller that adjusts and controls a SPAD photon detection rate in accordance with a first photon detection rate indicating a rate of the number of at least one pulse signal output by the second SPAD array upon incidence of the at least one second light beam relative to the number of the at least one pulse light beam are included.
