How Lidar Technology Measures Speed
Jon Cohen, who has challenged lidar evidence in thousands of speeding cases, explains the basic principle: unlike radar, which uses radio waves, lidar uses pulses of infrared laser light to measure speed.
The device emits a series of laser pulses toward a target vehicle. Each pulse travels to the vehicle, reflects off it, and returns to the device.
