Patent ID: 8379193

Claim:
A method comprising: illuminating a target area comprising at least one unknown sample to thereby generate a plurality of first interacted photons wherein said first interacted photons are selected from the group consisting of: photons absorbed by said target area, photons reflected by said target area, photons scattered by said target area, photons emitted by said target area, and combinations thereof; assessing said plurality of first interacted photons using a spectroscopic device wherein said assessing comprises obtaining a test SWIR data set representative of said target area; analyzing said test SWIR data set to thereby identify an area of interest in said target area; illuminating said area of interest using a laser light source to thereby generate a plurality of second interacted photons wherein said second interacted photons are selected from the group consisting of: photons absorbed by said area of interest, photons reflected by said area of interest, photons scattered by said area of interest, photons emitted by said area of interest, and combinations thereof; assessing said plurality of second interacted photons using a spectroscopic device wherein said assessing comprises obtaining a test Raman data set representative of said area of interest; analyzing said test Raman data set to thereby identify said area of interest as comprising at least one of: an explosive material, a concealment material, a formulation additive of an explosive material, a binder of an explosive material, a non-explosive material, and combinations thereof.
