AI Technical Summary

Technical Problem

Existing lidar systems suffer from a high overall failure rate due to the complete loss of communication functionality caused by the failure of either the LED or the PD on the rotating body, making them unsuitable for applications requiring high reliability.

Method used

The coded laser is split into two beams, one for ranging and one for communication, using a beam splitter. A single photodiode design simplifies the optical path and receiving system, reduces hardware complexity, and achieves independence and stability for ranging and communication through the coded laser.

Benefits of technology

This reduces the probability of hardware failure in lidar, improves system reliability and overall performance, and ensures the stability and efficiency of ranging and communication functions.
