SYSTEM AND METHOD FOR ADAPTIVE ILLUMINATION IN A LIDAR SYSTEM

Abstract:

Techniques are described to adjust one or more parameters to vary the illumination output within at least one of the regions-of-interest (ROIs) in a field-of-view (FOV) and to adjust one or more corresponding receiver parameter(s). By associating different parameters between two or more ROIs within an FOV, this disclosure describes a LIDAR system having an adaptive FOV. An adaptive FOV can allow a LIDAR system to vary its performance between ROIs. For example, in an FOV having at least a first ROI and a second ROI, the LIDAR system can output more optical power in the first ROI then the second ROI to increase the signal-to-noise (SNR) ratio and therefore achieve a longer detection range.
