Description
Summary:One of the most important problems of detecting weak light pulses is the determination of the accurate signal transit time. In this case, photodetectors capable of detecting single photons are characterized by two main parameters: the photon detection efficiency and transit time spread. A unified technique for measuring these parameters is proposed. The technique is based on the probabilistic distribution of transit times, which allows separation of characteristics of single-photon processes as multiphoton light pulses are fed and under conditions of high dark noises, which seems important, in particular, when operating with solid-state photomultipliers.
