Influence of Substrate Material on the Sensitivity of the Raman Lidar Technique for Detecting Traces of High-Energy Materials

Experimental results on the remote detection of surface traces of some high-energy materials are presented. The detection was performed with the use of a Raman lidar based on a narrow-linewidth excimer KrF laser and a multichannel spectrum analyzer with diffraction spectrograph and time-gated ICCD camera. The sensitivity of the lidar system is estimated for a detection range of 10 m. The influence of a substrate material on the detection sensitivity is analyzed.
