| Understanding Laser Laser guns rely on a very narrow beam of light, (or small pulses of light) to target vehicles. This beam of light is fired at a vehicle at the speed of light. Once the light hits the target, the light bounces (reflects) off the object and back to the laser gun. As the reflected light pulses are received by the laser gun, it can calculate a vehicles speed based on the amount time it takes for the light pulses to come back to the gun. Multiple pulses are sent in less than a second. While the officer is firing the laser gun, the light bounces off of the target vehicle, and other objects around it. A good laser detector can easily see the laser source, and the reflected light signals that bounce off other objects. That's because the laser beam is scattered into thousands of sharp, bright, piercing beams of pencil light streaking out in thousands of directions when it hits any object in its path, including any part of any car. | ||
