In a LIDAR system, during at least one scanning cycle, light is projected at a first light intensity toward a first region of the field of view, and an object in the first region is identified based on the reflections of the light projected at the first light intensity during the at least one scanning cycle. A determination is made that the object is located at a distance greater than a distance threshold from the LIDAR system and correspond to a signal-to-noise ratio below a desired level, and a region of interest containing the object is defined. Light allocation to the defined region of interest is increased relative to other regions in the field of view by causing the light to be projected toward the defined region of interest at a second light intensity, higher than the first light intensity.

A method for detecting objects using a LIDAR system includes controlling a light emission assembly including at least one light source in a manner enabling spatial light modulation to a field of view of the LIDAR system to vary during different flash light emissions of the light emission assembly and determining a nonuniform spatial light modulation for the light emission assembly. The light emission assembly is instructed to emit to the field of view at least one flash light emission in accordance with the nonuniform spatial light modulation, the at least one flash light emission simultaneously illuminating different segments of the field of view of the LIDAR system at different intensities. An object is detected in the field of view based on a plurality of reflection signals of the at least one flash light emission.
