Abstract
A measurement device according to an embodiment includes: a light receiving element () 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 () that is configured to detect the current and invert an output signal when the current crosses a threshold value, a delay unit () that is configured to delay timing of the inversion detected by the detection unit, according to a clock, and a control unit () that is configured to control an operation of the light receiving element, based on the timing of the inversion delayed by the delay unit.
