Abstract
A LIDAR system is provided. The LIDAR system comprises at least one processor configured to: control light emission of a light source; scan a field of view by repeatedly moving at least one light deflector located in an outbound path of the light source; while the at least one deflector is in a particular instantaneous position, receive via the at least one deflector, reflections of a single light beam spot along a return path to a sensor; receive from the sensor on a beam-spot-by-beam-spot basis, signals associated with an image of each light beam-spot, wherein the sensor includes a plurality of detectors and wherein a size of each detector is smaller than the image of each light beam-spot; and determine, from signals resulting from the impingement on the plurality of detectors, at least two differing range measurements associated with the image of the single light beam-spot.
