A green-band Scheimpflug lidar system: feasibility studies for atmospheric remote sensing
This work demonstrates a green-band Scheimpflug lidar system by employing a high-power continuous-wave 520-nm laser diode as the laser source and an image sensor as the detector. Atmospheric remote measurement was continuously performed from October 28th to November 3rd on a near horizontal path, while a severe haze occurred during this period. The time-range backscattering map is obtained and the distribution of the atmospheric extinction coefficient is retrieved from the lidar signals based on the Fernald inversion algorithm. The spatial-averaged aerosol extinction coefficient shows good linearity with the PM10/PM2.5 concentrations measured by a local national pollution monitoring station.
