Application analysis of quantum Lidar technology in air pollution monitoring

This study mainly focuses on the experimental analysis of the application of quantum lidar technology in air pollutant monitoring. Through the discussion of the principle of lidar meteorological detection and quantum lidar, the practical foundation is laid, and it is found that the latitude and longitude of each hot spot corresponding to the scanning profile of lidar can be obtained by calculation, and then the area of hot spot area can be calculated. Moreover, all the analysis results of a scanning lidar can be spliced into a circular pseudo-color map according to the absolute angle of each section and superimposed on the vector map, which is convenient for managers to observe the distribution of pollution intuitively. At the same time, through the experiment of lidar detection, it is found that when atmospheric pollutants appear, the original lidar echo signal will fluctuate obviously, and the polluted particles will make the laser scatter strongly, which will lead to the rapid increase of the intensity of the atmospheric backscattered echo signal, and the lidar detection can be realized by generating strong mutation signals.
