Paper Abstract

In this paper we present an IR-radiometer circuit that allows to carry out measurements of week photoelectric signals on considerably lower level of the inherent noise than known IR- detector systems for (delta) equals 4.5 - 5; 8 - 13 micrometers ((mu) ) atmospheric windows. Contrary to similar developments, here additional circuit solutions suggested to decrease preamplifier noise, for the amplitude stabilization of photosensitive bridge feeding pulses to correct basic and useful signals phases as well as to improve characteristics of the synchronous detector.
