What happens at the moment the LIDAR light pulse is transmitted?

At the moment the LIDAR light pulse is transmitted, a timer begins to count. This is a crucial aspect of how LIDAR technology measures speed. The device emits a pulse of light, and the timer is activated to start measuring the time it takes for that pulse to travel to the target vehicle and then return to the device. The time measurement is fundamental for calculating speed, as the device uses the time it takes for the light to travel to the object and back (round trip) to determine the distance. By knowing the distance and the time taken, the LIDAR system can accurately compute the speed of the vehicle being targeted. This understanding of the timing mechanism is essential for the effective functioning of LIDAR in speed detection and enforcement.
