Abstract
A LIDAR system for use in a vehicle may include at least one light source configured to project light toward a field of view for illuminating a plurality of objects in an environment of a vehicle and at least one processor configured to control the at least one light source in a manner enabling light flux of light from the at least one light source to vary over scans of a plurality of portions of the field of view. The LIDAR system may receive information indicating that a temperature associated with at least one system component exceeds a threshold, and in response to the received information indicating the temperature exceeding the threshold, modify an illumination ratio between two portions of the field of view such that during at least one subsequent scanning cycle less light is delivered to the field of view than in a prior scanning cycle.
