Abstract:
A photodetector includes: a photoreceptor provided with a SPAD that is configured to respond to incidence of a photon, and as the response of the SPAD, configured to output a pulse signal; and a pulse rate control circuit configured to control sensitivity of the photoreceptor to have a pulse rate as the number of pulse signals outputted per unit time from the photoreceptor to be a set value set in advance, (i) in a set range including the set value, (ii) in a set range of the set value or more, or (iii) in a set range of the set value or less.
