Abstract: The present disclosure provides for a system and method for detecting, identifying and/or distinguishing between ignitable liquid residues on various types of substrates. A method may comprise generating a fluorescence data set representative of a substrate, which may comprise a fluorescence hyperspectral image. This fluorescence data set may be analyzed to determine the presence and/or identity of an ignitable liquid residue. Regions of a substrate comprising an ignitable liquid residue may further be interrogated using Raman techniques. This may comprise generating and analyzing a Raman data set representative of a region of interest of a substrate to thereby identify an ignitable liquid residue. A system may comprise an illumination source, a tunable filter, and a first detector configured to generate a fluorescence data set. The system may further comprise a second detector configured to generate a Raman data set representative of a region of interest of a substrate.
