The paper presents results of studying the feasibility of remote detection of explosive vapors in the atmosphere based on the lidar principle using the method of laser fragmentation/laser-induced fluorescence. A project of the mobile, automated, fast-response scanning UV lidar for explosives detection at distances of 10–50 m is presented. Experimental data on the detection of trinitrotoluene (TNT), hexogen (RDX), and Composition B (CompB) vapors at a distance of 13 m are given. The threshold sensitivity of the lidar detector of explosive vapors is estimated. For TNT vapors, the threshold sensitivity of the lidar detector is estimated to be 1∙10−12 g/cm−3 for the detection probability P = 97%.
