Detection of the pulses of light under the photon counting mode

The method of registration of weak light pulses in a mode of the photon counting is discussed. The general principles of the photon counting, the necessary experimental equipment and possible techniques of the counting are considered. The methods of photon counting, namely, synchronous photon counting using chopper, time-resolved photon counting and time-correlated photon counting (TCPC) is described. The basic characteristics of the photon counting are described. The appendix of techniques of the photon counting for experiments in the field of a photon echo is considered. The Photon Counter (worked out in Kazan State University) and obtained low-level light registration experiment are described.
