Abstract: A system and method for identifying explosive or other target materials includes the steps of irradiating a first location and a second location spaced apart from the first location from a sample suspected of including explosives with ultraviolet, visible or infrared light, measuring reflected light emanated from the first sample location (R1) and reflected light emanated from the second sample location (R2), and calculating a normalized difference in reflectivity (ΔR/ R ), wherein R = (R1+R2)/2 is an average reflectivity. A differential reflection spectrum (DRS) is then generated for the sample where ΔR=R2-R1 is the difference of the reflectivities of the first and the second sample location. One or more explosives or other target materials if present are identified in the sample based on comparing the DRS for the sample to at least one reference DRS.
