Study of the evolution of the surface concentration of traces of high energy substances in fingerprints by polarization macrophotographic and lidar methods

The results of the study of the evolution of the surface concentration of cyclotrimethylenetrinitramine (RDX) traces in fingerprints by the polarization macrophotographic method and by the method of laser fragmentation/laser-induced fluorescence are presented. A technique for estimating the surface density of RDX traces in fingerprints based on a pixel-by-pixel analysis of macrophotographs taken in polarized light is described. Experimental data on remote detection of RDX particles in fingerprints are presented. Comparison of the data of direct measurements of the total area of the trace with the data of the responses of the LF/LIF lidar detector gives good conformability. The authors declare no conflicts of interests.
