激光雷达作为一种主动式遥感技术被广泛应用于大气及海洋环境监测中。三维扫描系统丰富了测污激光雷达 探测污染气体浓度的空间范围。介绍了承担研制的测污激光雷达系统结构。给出了扫描控制系统的硬件构 成。介绍了LabVIEW设计测控程序常用的两种编程结构。采用LabVIEW基于事件的生产者/消费者模式结 合状态机的结构设计了测污激光雷达三维扫描控制系统。测试结果表明,测控系统稳定,可靠且易于系统集成。

Lidar as an active remote sensing technique has been widely applied in survey of the atmospheric and marine environment. Three dimensional scanning system enriches the special area for air pollution monitoring Lidar. The structure of the Lidar developed is introduced. And the hardware system of the scanning control system is also presented. Two common structures of LabVIEW are introduced for measurement and control program. The three dimensional scanning system for air pollution monitoring Lidar is developed with the mode of producer-consumer based on events and state machine structure with LabVIEW. Test results show that the developed system is stable and can be easily integrated with other systems.
