Abstract:
Detecting threat materials used in explosives is performed by receiving a sample, and selecting an area of interest on the sample suspected of containing a threat material indicative of an explosive. Detection also includes interrogating the area of interest with a Raman laser producing a Raman spectrum, and comparing an amplitude of a first spectral region in the Raman spectrum to a first predetermined threshold. Detection further includes performing a verification, if the determination indicates that the area of interest includes the threat material, by checking the interrogated area of interest for a secondary indicator of the presence of the threat material, by comparing an amplitude of a second spectral region in the Raman spectrum, which is different from the first spectral region in the Raman spectrum, to a second predetermined threshold, and activating an indicator if the verification indicates that the area of interest contains the threat material.

Claim (Index 7):
The method of  claim 6 , wherein:\n performing a verification, if the determination indicates that the area of interest includes the threat material, by checking for a secondary indicator of the presence of the threat material, comprises:\n interrogating at least a portion of the Raman spectrum measured in the second spectral region, which is set to a wave number shift around 3225 cm \u22121 ; and \n comparing an amplitude of a second spectral region different from the first spectral region, measured during the interrogation, to a second predetermined threshold, comprises:\n determining if the sample includes ammonium nitrate by comparing the amplitude of the measured portion of the Raman spectrum at approximately 3225 cm \u22121  to the predetermined threshold, where the second threshold is set to a value corresponding to a feature in the second spectral range indicative of ammonium nitrate.
