Lidar system and crosstalk reduction method thereof

Abstract

A LiDAR system includes a microcontroller, a laser light source, a lens module, and a receiver. The lens module includes a laser beam splitter module and a receiver lens module, the laser beam splitter module receiving a laser light and diffracting the laser light into multiple diffractive lights emitted toward a target. The receiver lens module receives a reflective light signal of the diffractive lights reflected from the target and emits the reflective light signal towards the receiver. A frame of the LiDAR system includes a plurality of subframes. The microcontroller compares the average distance values at the same sampling area of each subframe within the frame, eliminates the subframes with abnormal average distance values, and fuses the other subframes with similar average distance values as a final distance value of the frame.
