Evaluation of energy characteristics of quantum optical means for controling the emissions of car exhaust gases

Abstract

The analysis of the theoretical foundations of laser measurements of the composition of the air and the possibility of its use in emergency situations caused by emissions of a large number of polluting gases, aerosols and microparticles by diesel engines, internal combustion engines of automobile transport is carried out. A method for solving the problem of operational monitoring of the gas composition of impurities and aerosols in the control zone using a single complex of laser measuring equipment is proposed.

The most promising method for diagnosing air pollution is remote sensing methods. Among remote methods, laser methods occupy a special place. One of the most effective means of remote monitoring of the degree of environmental pollution are laser monitors, also called lidars (similar to radars).

 Sensing methods are divided, depending on the method of obtaining information into: active - while environmental objects are probed with electromagnetic radiation and passive, information is obtained by recording the result of the interaction of radiation from natural sources or the own radiation of the analyzed impurities.

The article considers the possibility of using laser tools for the operational control of the degree of environmental pollution by exhausts of automobile engines. The given estimates of the energy parameters of the lidar to identify typical polluting components.
