Pollution Monitoring Using Nd:YAG Based Lidar Systems
Laser-radar techniques for remote measurements of atmospheric and hydrospheric conditions, especially pollution levels, are becoming increasingly important. Recently we have reviewed different aspects of laser remote sensing1,2. A program of laser-based pollution monitoring was initiated in 1975 within our research group at Chalmers University of Technology, Göteborg. A lidar system employing a 25 cm diameter Newtonian telescope and a dye laser (flashlamp- or N2-laser-pumped) was constructed. A specially designed microcomputer was used for transient averaging and system steering. The system was used for technique developments, and several field tests on air-pollution monitoring and hydrospheric probing were performed. The lidar system and examples of atmospheric particle, NO2 and SO2 monitoring are presented in Ref. 3, which also contains references to more detailed laboratory reports.
