LIDAR SYSTEM WITH HUMIDITY COMPENSATION

Abstract:

In one embodiment, a lidar system includes a light source configured to emit an optical signal that is directed into a field of regard (FOR) of the lidar system. The lidar system also includes a receiver configured to: receive a portion of the emitted optical signal scattered by a target located in the FOR a distance from the lidar system; and produce an electrical signal corresponding to the received optical signal, where the electrical signal is related to a preliminary value of an optical characteristic of the received optical signal. The lidar system further includes a processor coupled to the receiver and configured to: determine the distance to the target; receive a humidity value; and determine a corrected value of the optical characteristic of the received optical signal based at least in part on the electrical signal produced by the receiver, the distance to the target, and the humidity value.
