Abstract

The main results of theoretical investigation of the sensitivity and information capacity of the thermal imagers and other electronic-vision systems are presented. The spectral dependencies of radiant-noise-equivalent temperature difference are calculated. It has been found that the thermal vision does not yield to the daylight human vision in information potential under the conditions of thermal balance of the earth. The ultimate values of the specific information capacity of electronic-vision systems are evaluated, in that number under low radiation fluxes and with the limitation of the size of element sensitive areas by diffraction.
