Laser Variables: Police laser guns use a 904 nanometer wavelength of monochromatic infrared light transmitted at specific pulse rates. Laser guns compute speed by knowing distance. Distance is known by the time it takes for one pulse to travel to a specific target and reflect back to the laser's guns computer. The computer remembers the time each pulse leaves the gun and is looking for this specific pulse to return. The color of a target vehicle is a great determinate in the lasers gun's ability to target. Black absorbs all colors, while white reflects all colors. Targeting a white vehicle is very easy for a laser gun even without headlights or a front license plate.
