Abstract
Hybrid Image Tubes (HIT), being Image Intensifiers (II), output cathode-luminescent screen of which is replaced by periodic structure of semiconductor electron-sensitive elements (ESE), meet more and more wide application in the fields where it is necessary to receive and process weak optical images (illumination level of about 10-6 lx). In this connection it is expedient to estimate HIT as photon counter, more precisely as photon group counter (with photons number in the group (gamma) -1, where (gamma) -quantum output of the used photocathode on a certain wavelength). One- electron (counting) registration mode is possible if impulse amplitude at ESE output exceeds fixed level of amplitude discrimination which cuts off measuring equipment noise together with ESE noise. This imposes strict requirements on coefficient of amplification value of element Kamp and on dispersion D of output impulses amplitudes.
