Abstract
Experimental results on the remote detection of surface traces of some high energetic materials using a Raman lidar constructed on the basis of an excimer KrF laser with the narrow generation line and a multi-channel spectrum analyzer based on the diffraction spectrograph and a time gated ICCD camera are presented. The sensitivity of the lidar system for a detection range of 10 m was evaluated. The influence of a substrate material on the sensitivity of the detection method is analyzed.
