Abstract

Analysis of signal-to-noise ratio in optical receivers Z. Bieleckil, W. ~o~osowski', E. sqdek2 & M.

Abstract The paper describes principles of minimisation of noise produced in infrared detection systems. Analysis of operating conditions affecting signal to noise ratio (S/N) has been carried out. Also analyses for maximisation of S/N in advanced methods of optical signals detection have been made. Many practical solutions have confirmed theoretical predictions. 1 Introduction Infrared radiation receivers are used in many up-to-date fields of science and technology determining current level of technological progress. The most important fields of their applications are industrial automation, robotics, space technology, medicine, and military technology. Three various types of detectors (both thermal and photon ones) are
