Abstract
The results of remote detection of objects containing explosives by means of a combined use of a lidar detector of explosive traces and a portable express gas chromatograph are presented. It is shown that the lidar detector of explosive traces confidently detects the simulators of TNT, hexogen, and PTEN from a distance of 5 m when sounding the surface of a sample. It is shown that laser action on the surface of the sample causes vapor desorption and provides a reliable detection of samples by means of the gas chromatograph. It is shown that the joint use of the method of laser sounding and gas chromatography makes it possible to increase the reliability of detecting explosives. The prospects have been determined of using the gas chromatography method in the research on the development of laser sounding techniques.
