Abstract
This disclosure provides methods and apparatuses relating to LiDAR. In an example method: transmitting a detection pulse to the outside of the LiDAR, wherein an intensity of the detection pulse is adjustable, switching a bias voltage of a receiver of the LiDAR from a first bias voltage to output a second bias voltage based on a time of transmission of the detection pulse, wherein a detection performance of the receiver is lower at the first bias voltage than at the second bias voltage, receiving an echo of the detection pulse reflected from an obstacle, and converting the echo into an electrical signal by the receiver device.
