Laser remote detecting gas leakages, analysis of the 'sensitivity - distance' characteristic

摘要

On the base of a generalized quality criterion of the measuring system there is carried out analysis and mathematic simulation of the detected point range variation and of operation distance of the laser remote absorption gas-analysers. There are estimated upper and lower limits of concentrations under measurement as well as working distance range. Ways of perfection of remote gas leakage detectors are shown.
