Abstract
Provided is a light detection and ranging (LiDAR) system including: a light source; a beam steering device configured to steer light emitted from the light source toward an object; a light detector configured to detect light reflected from the object; and a processor. The beam steering device may include an optical phased array, including a plurality of channels, and a signal input unit which applies a plurality of driving signals to the plurality of channels. The processor is configured to perform an optimization operation including analyzing the light detected by the light detector, calculating at least one correction value, and controlling the plurality of driving signals according to the at least one correction value, in order to correct an error of the beam steering device.
