Development and case study of side-scatter lidar system based on charge-coupled device

The backscatter lidar technique is widely applied to atmospheric aerosol detection, but the blind and transition regions restrict its detecting range and precision in near distance. Side-scatter lidar technique without above shortage can detect aerosol continuously in near distance, and has good precision. A side-scatter lidar system was developed, which is composed of transmitter, receiver, geometric calibration, and data acquisition subsystems. Comparison experiment with backscatter lidar indicates that the data acquired from this lidar are reliable and the near detection effective range is from 0.02-4 km. This system can be used for study the spatio-temporal distribution of atmospheric aerosol in near surface further.
