摘    要:目前,我国空间光学遥感器正向着大型化、高精度的方向发展,辐射定标装置也随之发展进步。本文系统地介绍了大口径空间相机用积分球辐射定标装置辐射性能的测试方法。研制出一套积分球辐射性能测试装置,用于测试大口径积分球的均匀性、余弦特性和稳定性,并给出了积分球辐射定标光源的输出不确定度。文中检测的积分球辐射定标光源内径为3 000mm,出光面直径为1 000mm,得到该积分球辐射定标光源的均匀性为0.11%,在±20°范围内余弦特性最大偏移为1.1%,整个系统的输出不确定度为5.94%。

关 键 词:积分球  均匀性  稳定性  余弦特性  不确定度

Abstract:At present, the space optical remote sensor of china is heading for a large-scale, high- precision development. With that, radiometric calibration device also develops. Systematically, this pa- per describes the test method that is used to detect the radiance of the large aperture integrating sphere. A testing system is manufactured to test the radiation characteristics of the large aperture integrating sphere, including not only the uniformity, the stability, the cosine characteristics, but also the output un- certainty of the integrating sphere light radiation source calibration system. The diameter of the integrating sphere is 3 000mm, the Opening diameter of the integrating sphere is Obtained results indicate that the uniformity is 0. 11%, the maximum offset of the cosine characteristics is 1.1% at ±20°, and the output uncertainty of this system is 5.94%.
Keywords:Integrating sphere  Uniformity  Stability  Cosine  Uncertainty
