How do laser guns work?
Laser guns do not use the Doppler principle like radar guns do. Instead, they use “time difference of arrival”. The laser gun sends out a pulse, and calculates the “time of flight” for the pulse to be reflected back to the laser gun. Since the speed of light is a known value, the distance between the laser gun and it’s target can be calculated by the time of flight. The laser gun takes multiple distance measurements, and by comparing the different distance measurements over time, it can determine the speed of the target.
