We propose using wavelength-modulation laser absorption spectroscopy in combination with quadrature detection of scattered light for remote industrial pollution monitoring in the atmosphere with a compact lidar-based gas sensor, which can be mounted on board an unmanned aerial vehicle. The instrument can be used for detecting leaks in product pipe lines; monitoring toxic gases near landfill sites, waste incineration plants, and other hazardous man-made facilities; analysing the gas atmosphere in industrial buildings and structures; and monitoring engineering processes at a sensitivity level of tens of ppm m in gas concentration measurements at characteristic distances of tens of metres.

我们建议将波长调制激光吸收光谱与散射光的正交检测相结合，使用基于激光雷达的紧凑型气体传感器进行大气中的远程工业污染监测，该气体传感器可安装在无人驾驶飞行器上。该仪器可用于检测产品管道的泄漏；监测垃圾填埋场、垃圾焚烧厂和其他危险人造设施附近的有毒气体；分析工业建筑物和结构中的气体气氛；在数十米特征距离的气体浓度测量中，以数十 ppm m 的灵敏度水平监测工程过程。
