Abstract
We present experimental results on the remote detection of surface traces of some high energetic materials using a Raman lidar designed on the basis of an excimer KrF laser with a narrow generation line and a multi-channel spectrum analyzer based on diffraction spectrograph and time gated CCD camera. Sensitivity of the system is evaluated for the detection range 10 m. A detection limit of 0.5 μg/cm2 is reached for the surface density of traces of nitrogen-containing chemical materials at the signal accumulation over 1000 laser pulses.
