Abstract
Provided are a single photon detector and an operation method thereof. The single photon detector may include a gate signal generator for generating a gate signal having a first pulse width (ΔP) with respect to a first time point (t); and a first photon detector for detecting the single photon while operating in a Geiger mode by receiving the gate signal, and outputs a photon detection signal at a second time point (t), wherein the first photon detector outputs the photon detection signal at the second time point (t) spaced apart at a predetermine time interval (ΔT) from the first time point (t).
