Studying light flashes from a screen of image converter tube for single photon registration

In various fields of science and engineering a need often arises to record images in a single- photon mode, especially if an addition to spatial information and analysis also demands time data. The last two decades have resulted in a wide development of photon television counters (PTC), incorporating an image converter (IC) and camera tube, matched together. The basic component of the PTC determining its parameters is an IC tube whose task consists in the maximum possible efficient conversion of the light quantum flux to photoelectrons, amplifying the latter with a minimum dispersion in space, time, and energy and, finally, converting the amplified photoelectrons to light flashes with the help of a phosphor, also with a minimum dispersion.© (1993) COPYRIGHT SPIE--The International Society for Optical Engineering.
