Estimation of Possibility of Use of Objectives at Video Image Displaying on Photo Registering Devices

Abstract

. The estimation of possibility of use of objectives is considered at video image displaying on photoregistering devices by the analysis of models of ideal and real objectives with an estimation of speed of displaying of the image on a photosensitive zone of charge-coupled devices (CCD). The basic concepts and the definitions which are required for estimation of video image on charge-coupled devices are resulted. Various kinds of CCD are considered and analyzed. The analysis of existing CCD’s with a virtual phase and infra-red CCD’s of domestic production is carried out. Threshold value of a stream of radiation depending on length of a wave, diameter of an aperture of objectives and focal lengths is defined, and also speed of displaying of video image for a domestic production CCD ISD017 is estimated both at model of an ideal objective, and at model of a real objective.
