Remote detection of traces of high-energy materials on an ideal substrate using the Raman effect

Abstract

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