LIDAR speed measuring devices measure the time a light pulse travels to a selected target and back and determine the velocity of the moving target by repeating the measurement in a sequence of pulses. For use in road speed measurement, the meters must be calibrated using a time-delay simulator specially designed for this purpose. The calibration of the meters requires regular calibration of the simulator itself, which is the topic of this thesis.
I performed the calibration by measuring the time delays directly on the simulator with a very precise measuring clock and comparing them with those calculated in advance on the basis of theoretical assumptions. The comparison of the results showed that this approach can only be used to calibrate the part of the simulator, which takes care of the production of time delays, but not the optical unit of the simulator intended for communication with the speed measuring device.
