Abstract
A method of operating a light detection and ranging (LIDAR) system is provided that includes generating a beam of polarized light; and transforming a polarization state of the beam of polarized light at a rate faster than a rate of data collection at a plurality of detectors configured to detect light reflected from a target for the purpose of speckle-reduction.
