Abstract
The present disclosure relates to a laser receiving device and a LiDAR. An isolation component is provided between a plurality of parallel sensor groups, and an isolation component is provided between a plurality of amplifier groups in parallel, so that a plurality of parallel receiving channels each form an independent current loop, thereby reducing noise crosstalk among signal receiving channels and improving the signal-to-noise ratio of the laser receiving device.
