Standoff detection of explosives in open environment using enhanced photodissociation fluorescence

The Enhanced Photodissociation Fluorescence method is a novel approach to overcome several limitations associated with remote optical detection of vapors emanating from NO containing explosives. By using an additional laser source to enhance their evaporation, a sufficient concentration-level is achieved to extend the scope of optically detected materials. The enhanced system has successfully demonstrated detection of low vapor pressure explosives (RDX, PETN, C4, Composition B and SEMTEX) from a distance of 30m in outdoor, day-light conditions.
