New generation of the portable backscatter lidar with eye-safe energy level for environmental sensing

摘要

A compact nanoJoule laser radar system capable of detecting invisible aerosol and dust layers within a kilometer range was developed. A new design for an eye-safe portable backscatter Lidar for measurements of atmospheric propagation and aerosol extinction was used. The experimental data of the aerosol/dust detection, cloud height and time variation of the background solar radiation obtained in both the active and passive lidar operation mode are presented.
