The aim of this paper is to analyze the performance of Raman Light Detection and Ranging (LiDAR) technique and Raman Spectroscopy technique to detect trace explosives such as Research Department Explosive (RDX) and Trinitrotoluene (TNT). In various situations, when explosives are prepared, transported or handled, a quantifiable amount of explosive material ends up on surfaces. The main focus lies on the comparison between the two techniques for detecting these traces. This paper is based on the design of Raman LiDAR so that it can be used for real time application, keeping in mind the commercially available fibers. The merits and demerits of both the techniques have been studied. We are investigating which method is best suited for detecting remote trace explosives. © Research India Publications.
