Abstract:
1. An enhanced photoemission spectroscopy (EPS) system to identify or quantify a substance comprising: an optical probe configured to perform at least three light or photoelectric processes, wherein the processes include Raman scattering detection, fluorescence detection and spectral surface reflectance detection to generate spectral data from each process, wherein the optical probe includes a light source to illuminate a target with sufficient energy transmitted at a wavelength to generate return energy to support the at least three processes, and an amplitude and wavelength calibrated (AWC) spectrometer to detect the return energy and to generate the spectral data; a computer coupled to the optical probe to access at least three data modules corresponding to each process, wherein the data modules are configured to analyze the spectral data from the at least three processes and derive a target signature for the target; a signature database to store signature data of known substances, wherein the target signature is compared to the signature data; and a display to show results from the comparison between the target signature and the signature data.
