Standoff Laser Spectroscopy System

The system works by shining an infrared laser on a distant object. The reflected light from the object's surface is captured by a telescope, focused onto a detector and analyzed to determine the chemical composition of the surface of the object. As an anti-terrorism tool, the device may be used to detect and identify surface residues of dangerous materials, such as chemical agents, biological agents or explosives, from distances up to 100 meters. The system has a wide array of uses from scanning passengers and luggage in airport terminals to searching for improvised explosive devices (IEDs) along roadways to scanning vehicles on the road or at border crossings and checkpoints.
