Abstract
Embodiments of the disclosure provide a light detection and ranging (LiDAR) system. In an example, the LiDAR system includes a laser source, a scanner, a beam deflecting unit, and a controller. The laser source is configured to emit a laser beam towards an object. The scanner is configured to receive a returned laser beam from the object, and deflect the returned laser beam towards a beam deflecting unit to form a first laser beam traveling along a first direction. The first direction deviates from a reference direction by a deviation angle. The beam deflecting unit is configured to receive the first laser beam, and deflect the first laser beam to form a second laser beam towards a photosensor. The controller is configured to dynamically control a deflection angle of the beam deflecting unit to cause the second laser beam to be deflected towards the photosensor to compensate the deviation angle.
