Abstract
Embodiments of the disclosure provide receivers for light detection and ranging (LiDAR). In an example, a receiver includes a beam converging device, an AO beam deflecting unit, and a beam sensor. The beam converging device is configured to receive a laser beam from an object being scanned by the LiDAR and form an input laser beam. The AO beam deflecting unit is configured to generate a diffraction grating along a propagating direction of an acoustic wave, receive the input laser beam such that the input laser beam impinges upon the diffraction grating, and form an output laser beam towards the beam sensor. An angle between the input and the output laser beams is nonzero.
