【摘要】 为了满足包括太阳直射和天空散射在内的2π球面度立体角范围的入射光线的测量需求,要求太阳紫外光谱辐射测量装置的入射光学系统必须具备较好的余弦响应特性。研制的入射光学系统由聚四氟乙烯积分球、磨砂石英球冠型余弦漫射器和修正环组成,积分余弦误差更多还原

【Abstract】 The ideal cosine entrance system is required for measuring the total radiation of the solar including the direct radiation and the diffuse radiation over a solid angle of 2π steradian on the surface of the Earth.A new combination entrance optics is developed with the integral cosine error更多还原
