Beschreibung
Zusammenfassung:	A measurement device according to an embodiment includes: a light receiving element (1000) that has flow of current caused by an avalanche multiplication caused according to a photon incidence while being charged to a predetermined potential and is returned to the charged state by a recharge current, a detection unit (1002) that is configured to detect the current and invert an output signal when the current crosses a threshold value, a delay unit (2101, 2102) that is configured to delay timing of the inversion detected by the detection unit, according to a clock, and a control unit (201a) that is configured to control an operation of the light receiving element, based on the timing of the inversion delayed by the delay unit.
