LIDAR SCANNER CALIBRATION

A LiDAR sensor can include a laser configured to output electromagnetic pulses and an optical splitter positioned to split each of the electromagnetic pulses into (i) at least one calibration pulse, and (ii) at least one external pulse directed toward an object external from the LiDAR sensor. The LiDAR sensor can further include a photodetector configured to detect the at least one calibration pulse and a reflected pulse based on the at least one external pulse reflecting from the object. The LiDAR sensor can further include a processor configured to adjust a bias voltage of the photodetector based on the at least one calibration pulse.
