摘要：

Atmospheric detection is the basis of air pollution control, lidar is a powerful tool for atmospheric detection. Because of blind area and transition area, lidar cannot get complete echo signals in the near range. Laser beam imaging technique based on charge coupled device (CCD) can solve the above difficulties caused by lidar effectively. Laser beam imaging technique is studied from theoretical analysis and simulation experiment, including imaging characteristics, the angle relationship between CCD image plane and lens plane, the influence of laser beam divergence angle on detecting spatial resolution. The comparison experiments show that laser beam imaging technique in detecting atmospherics is reliable and feasible. Furthermore, the application cases are given in detecting aerosol backscattering coefficient, aerosol extinction coefficient, aerosol phase function and PM2.5 mass concentration.
