摘　　要：为了克服背景光影响,通过增加百叶窗结构设计了用于全天候PM2.5浓度测量的侧向散射激光雷达装置。应用全天候激光雷达装置,实验获得了PM2.5测量浓度与实际浓度的拟合模型,进一步分析了关系式的综合偏差率、相关系数和拟合度等统计量。分析结果表明,相比于无百叶窗激光雷达装置,全天候激光雷达装置不仅能够有效地对夜晚PM2.5浓度进行测量,还能在白天PM2.5浓度测量时保证精度。In order to overcome the influence of background light,a side-scatter ing lidar for all-day PM2.5concentration measurement was designed by adding lo u vers.By using all-day lidar equipment,the fitting model between measured PM2.5concentration and real PM2.5concentration was obtained.The comprehensive devi ation rate,correlation coefficient and fitting degree of the relationship were further analyzed.The analysis results show that compared with the non-louvered lidar,the all-day lidar can not only measure PM2.5concentration at night effe c tively,but also ensure the accuracy of PM2.5concentration measurement during t he daytime.
