Paper Abstract

Cloud-Aerosol plays a very important role in the Earth's atmospheric system,so accurate data of global Cloud-Aerosol detection are of great importance to the climate.The 532nm detection channel of the Space-borne Lidar for Cloud- Aerosol has a low signal-to-noise ratio during the daytime,so it cannot be effectively detected during the daytime.In order to improve the signal-to-noise ratio of the 532nm detection channel,a high-stability"sandwich solid-etalon" structure is used in series with a narrow-band interference filter.A filter is designed with a high-precision thermal control structure,it's optical performance is detected.The results show that the performance parameters of the filter meet the design requirements: the mechanical structure is compact and reliable; the temperature control accuracy can reach 0.1 °C;the temperature tuning coefficient is 3.49pm/°C,that is, the temperature tuning range of +/-2.3 °C, which satisfies the central wavelength tuning range of 16pm; the incident angle should be controlled within +/-4.2mrad to meet the peak transmittance of more than 75%
