Abstract

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, dual-wavelength 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.
