【摘要】 本文简述了自行研制的环境监测激光雷达系统,其主要用于测量近地层大气中的O3、NO2、SO2以及气溶胶等。该系统在设计中有着不同于其它激光雷达的特点,第一,通过采用一台Nd:YAG激光器和H2、CH4、D2三根Raman管,即可产生多组波长,探测多种污染成分,从而实现了激光光源一体化,不仅使输出波长稳定可靠,还大大降低了发射光源的研制成本;第二,配有俯仰、方位扫描装置,可以对不同方位、不同仰角污染物进行测量,从而可得到污染物的二维或三维分布,这将对实现连续、实时、大范围监测大气污染有着重要的意义。最后列举了该激光雷达探测污染物的典型结果。更多还原

【Abstract】 This paper introduces an atmospheric monitoring lidar, which is primarily used to detect O3、NO2、SO2 and aerosol in the planetary boundary layer. This system has some typical characteristics. First, when adopting one Nd:YAG laser and three Raman cells, we can get several group of wavelengths which can be used to measure O3,SO2,NO2,and aerosol. Meanwhile, the output wavelengths are stable and reliable; the cost is also decreased. Second, it also can be used to measure contaminations at different zenith angle because this lidar system has 3-D scanning device. All these may have great significance for realizing continual, simultaneous, large-ranged atmospheric pollution detecting. In the end, some typical results about contaminations are enumerated.更多还原
