Abstract

We observe the forming of modulation pulses, by registration the optical pulses modulated in the time by photomultiplier which works in a photons count (PC) regime. The separate PC pulses are registered in the case of low light intensity. Pulse of modulation is formed if the intensity increases. It is shown, that the minimal registrative duration of the pulse is determined by one photo-electron (OPE) pulse. It imposes limitation on the possibility of signal registration. In the space language, it leads to minimal possible size of the picture spot, which is limited by the size of photosensitive grain of photoplate. The resolution of both a optical communication on a long distances or by the registration of supershort pulses will be limited also by the duration of OPE pulses.
