It measures time the light makes the roundtrip time to a car and back, which is achieved in less than a second. The accuracy of the police lidar comes from the thousands of time and distance samples that have been taken, as well as the available complex algorithms. It then calculates the signal’s Doppler shift to measure the speed. A radar, however, sends out a radio pulse instead of an infrared. The police lidar uses an infrared beam and the Doppler Effect to compare the difference in the frequency and then, of course, calculate the speed. People often mix up police lidar with police radar, but these two have different ways of measuring speed, although they have been used by traffic officers as speed measuring gadgets. The gun shoots out a focused beam of infrared that accurately measures speed up to the 10 th of an MPH. Upon hitting the trigger, the police can immediately get the speed of the vehicle it is targeting.
It’s much easier to use that the older Vascar ( ). The Police Lidar is an accurate device that gives fast feedback.

It is commonly called a speed gun, but officially, it is called Police Lidar which means “Light Detection and Ranging.” Other types of speed guns are used for professional sports as well, including baseball (pitching speed), tennis (serving speed), cricket (bowling speed), and other speed of athletes.
A police laser (or lidar) gun is generally the device that’s used by traffic enforcers and policemen to measure the speed of cars on the road.
