Abstract

One example method involves a light detection and ranging (LIDAR) device focusing light from a target region in a scene for receipt by a detector. The method also involves emitting a primary light pulse. The method also involves directing, via one or more optical elements, the primary light pulse toward the target region. The primary light pulse illuminates the target region according to a primary light intensity of the primary light pulse. The method also involves emitting a secondary light pulse. At least a portion of the secondary light pulse illuminates the target region according to a secondary light intensity of the secondary light pulse. The secondary light intensity is less than the primary light intensity.
