摘要
A system and process scans a target area at a distance of 3-30 m for one or more materials. Scanning is performed by a coherent transmit beam aimed with the help of a thermal camera. The active source of the beam is a supercontinuum (SC) laser. The transmitted source beam is modulated by a high-speed Fourier-transform spectrometer prior to interaction with the target. Target reflected source beam is detected by an infrared detector, along with a reference portion of the transmitted source beam, as a series of interferograms; passed through a digitizer for digitizing the interferograms; and processed to producing spectrograms, wherein the spectrograms are indicative of one or more materials on the target.
