Patent ID: 7760352

Claim:
A mobile, stand-off, single-event, dual pulse, on-the-move Raman spectrometry system, comprising: a laser module that is configured to generate a first wavelength of energy and a second wavelength of energy, wherein the first and second wavelengths of energy are directed, at substantially the same time, along an axis and through free space to a target substance, wherein the first and the second wavelengths of energy are pulsed sequentially with a temporal spacing of ΔT; a telescope for collecting a spectral energy pattern that returns along the axis and that results from interaction of the target substance with the first and second wavelengths of energy; a charge coupled device for receiving a collected spectral energy pattern from the telescope; and an analysis module for analyzing the collected spectral energy pattern and matching the collected spectral energy pattern to a known spectral energy pattern, wherein ΔT is less than about 10 μS, and wherein the laser module, telescope and analysis module are mounted on a vehicle and operate while the vehicle is in motion.
