The Use of Probing Laser Systems in the Complex Safety Problems

Abstract

The paper deals with the use of probing laser systems for solving complex security problems. In particular, laser systems for remote detection of unobtrusive obstacles and for detection of vapors of hazardous substances in the air are considered. The calculations showed the efficiency of the probing laser systems for the detection of small objects, like high-voltage wires, at distances up to 800 m. It was also shown that a compact laser probe system based on the principle of differential absorption and use of semiconductor DFB lasers, can be used to diagnose the vapors of a number of chemically hazardous substances in concentrations 1...1000 ppm at distances up to 1000 meters.
