摘要：
In specific LiDAR application scenarios, maintaining laser systems is either highly challenging or practically infeasible. Therefore, it is crucial to rigorously evaluate laser stability prior to operational deployment. This paper presents a high-precision, long-term monitoring system for laser parameters in large-aperture, dualwavelength LiDAR. The system integrates several modules designed to monitor critical laser parameters, as well as several environmental monitoring modules to track fluctuations in environmental parameters. Through the implementation of a diverse set of hardware and software operational strategies, the system guarantees secure and stable, unattended monitoring of LiDAR stability. By correlating laser parameters with environmental variations, this system offers a comprehensive and precise solution for assessing the reliability and stable operation capability of LiDAR systems.
