Abstract
Embodiments of the disclosure provide receivers for light detection and ranging (LiDAR). In an example, a receiver includes a beam reflecting unit having a plurality of digital micromirror devices (DMDs). The beam reflecting unit is configured to receive an input light beam returned from an object being scanned by the LiDAR, reflect a signal in the input light beam by at least one first DMD selectively switched to an 'ON' state at an operation angle to form an output signal towards a detector, reflect a noise signal in the input light beam away from the detector by at least one second DMD selectively switched to an 'OFF' state at a non-operation angle. The receiver also includes the detector configured to receive the output signal.
