中国昼光光谱测定装置

THE EQUIPMENT EOR MEASUREMENT OF DAYLIGHT SPECTRUM IN CHINA

为了测定中国的昼光和直射阳光光谱数据,中国科学院长春光学精密机械研究所和中国测试技术研究院联合研制了一套昼光光谱测定装置,安放在中国科学院长春净月潭遥感开放实验场。它是全自动化的野外工作台站使用的仪器系统,可覆盖全部到达地面的太阳光光谱区域。其光谱分辨率适中,光能利用效率高,安装和使用方便,可以同时分别测定直射阳光、天空散射光和昼光的光谱分布。

CIOFM and NITM have jointly developed a set of equipment for measuring the daylight,sunlight and skylight over China,which is arranged in the Remote Sensing Test Site of Jing Yue Tan,Academia Sinica,Changchum,Jilin.The system completely covers the spectral range of sunlight that reachs on the Earth surfacl,has the moderate spectral resolution,the high utilization factor of light,and can be used to measure the sunlight and skylight in the same time.In adition,it is easy for a field observatory to operate this fully automated system.
