Abstract
Systems and methods for determining an angle of the light transmitted by an illumination source of a scanning LIDAR system are disclosed. An example LIDAR system includes a pattern, provided in an optical path of the light transmitted by the illumination source as the light is transmitted out of the system, and configured to reflect at least a portion of the transmitted light to be incident on at least one of one or more optical sensors of the LIDAR system. The LIDAR system further includes, or is associated with, a controller, configured to determine an angle of the transmitted light based on a light detected by at least one of the optical sensors, where at least a portion of the light detected by the optical sensor(s) includes at least a portion of the light transmitted by the illumination source and reflected by the pattern.
