摘要
星载云-气溶胶激光雷达可精确获得全球云-气溶胶探测数据,利用干涉仪窄带滤波器来探测大气中的云和气溶胶可以提高回波信号的信噪比,并可进行全天探测。根据星载激光雷达对使用环境以及温度调谐的要求,选择固态标准具来实现所要求的干涉仪滤波器,对其材料的选择和结构的设计进行了分析,在封装设计时增加了温控结构,并对固态标准具进行了热应力耦合分析。综合考虑工作温度和入射角度的影响,给出最优的性能测试方案,根据方案测得固态标准具的温度调谐满足中心波长调谐范围。
Space-borne cloud-aerosol lidar can accurately obtain global cloud-aerosol detection data.Using narrow-band filter of interferometer to detect clouds and aerosols in the atmosphere can improve the signal-to-noise ratio of echo signals,and make all-day detection possible.According to the requirements of application environment and temperature tuning of spaceborne lidar,a solid-etalon is selected to realize the interferometer filter,and the material selection and structural design of which are analyzed.Furthermore,the temperature-controlled structure is added during packaging,and thermal stress coupling analysis is performed on the solid etalon.Considering the influence of operating temperature and incident angle,the optimal performance test scheme is given.It is found that the temperature tuning of the solid-etalon measured according to the scheme meets the central wavelength tuning range.
