Abstract
A LIDAR system and a method for operating a LIDAR system are disclosed. The LIDAR system broadly includes a transmitter that that emits a light pulse in response to a launch signal, a receiver that detects light pulses and determines a time of arrival for each detected light pulse; and a controller that generates an ordered sequence of frames. The controller generates a launch signal at the start of each frame and records information specifying a time of arrival relative to the start time for all light pulses received by the receiver until a stop time. After the stop time, the controller waits for the interframe delay time before generating another launch signal. The interframe delay time is different for each frame in the sequence of frames. The controller determines a distance between the transmitter and an object from the recorded information.
