Abstract
Methods for detecting and classifying an unknown substance in a sample include the steps of (a) providing a spectrum for each of a predetermined number of reference substances; (b) detecting an area of interest that contains the unknown substance; (c) targeting the area of interest; (d) determining a spectrum of the unknown substance from the area of interest; (e) comparing the determined spectrum of the unknown substance with the spectrum of one or more of the reference substances; and (f) classifying the unknown substance based on the comparison of spectra. Systems for performing these methods include means for providing a spectrum for a predetermined number of reference substances, means for detecting an area of interest on a sample that contains an unknown substance to be classified, means for targeting this area of interest, means for determining a spectrum of the unknown substance in the area of interest, means for comparing this spectrum with the spectrum of one or more of the reference substances, and means for classifying the unknown substance based on the comparison of spectra.
