METHOD FOR INCREASING PERFORMANCE OF SOLID-STATE PHOTOMULTIPLIER FOR RECORDIN LOW-PHOTON PULSES AND LIGHT MEASUREMENT SYATEM IMLEMENTING SAID METHOD Russian patent published in 2021 - IPC H01L27/00 

FIELD: optical communication.

SUBSTANCE: set of inventions relates to the field of optical communication, in which a solid-state photomultiplier is used as a receiving detector. The essence of the inventions consists in that the method for recording a stream of single photons by a solid-state photomultiplier additionally comprises a stage, on which the slowly changing component of the signal is filtered by means of a high-frequency band filter in order to extract individual pulses by shortening the front of the photoelectric pulse and thereby increasing the performance of the detector when recording the flow of low-photon pulses. It is possible to resolve the pulses following one another within dead time of the individual microcell of the detector.

EFFECT: increased performance of the matrix detector to an account frequency, which makes it possible to resolve pulses that follow one another within dead time of an individual detector microcell.
