摘要
Laser photothermal methods of stand off detection of trace explosive residues on surfaces are considered. The analysis is restricted to the most promising methods: photo-acoustic spectroscopy, deflection spectroscopy, and IR photothermal imaging of objects under resonant irradiation. Particular attention is paid to the choice of radiation sources and detectors. Comparative analysis of the existing stand off detection methods for explosive particles on the object surface is performed. Prospects of laser photothermal spectroscopy in this field are discussed.
