AI Technical Summary

Technical Problem

Vibrations generated during vehicle operation cause beam drift and jitter in laser communication systems, affecting the stability and reliability of the communication link.

Method used

A multi-axis vibration isolation platform is used in conjunction with a damping fixing device and an IMU sensor. The damping fixing device isolates external vibrations, the IMU sensor detects vehicle vibrations, and the multi-axis vibration isolation platform performs a reverse action to maintain the stability of laser emission. Digital PID or adaptive control algorithms are combined to suppress beam jitter.

Benefits of technology

It improves the stability and reliability of laser communication, reduces the impact of vibration on beam transmission, achieves passive vibration reduction, and enhances the performance of laser communication through active anti-vibration measures.
