APPARATUS FOR EVALUATING SINGLE-PHOTON DETECTOR, PROGRAM FOR THE SAME, AND RECORD MEDIUM

摘要

PROBLEM TO BE SOLVED: To provide an apparatus for evaluating a single-photon detector capable of correctly measuring the quantum efficiency of the single-photon detector even in a state in which the occurrence of afterpulses may not be ignored. SOLUTION: The apparatus for evaluating the single-photon detector is constituted of the single photon detector having an avalanche photodiode as a light receiving element, a storage device for storing photo detection times, and a computer for executing a processing program for determining the probability distribution of occurrence frequencies of detection time intervals from the photon detection times and determining the quantum efficiency of the detector from the probability distribution.
