摘要

介绍了一套测量太阳光衰减屏透过率的测量装置。该装置需要测量两组数据：安装太阳光衰减屏和不安装太阳光衰减屏透过的信号值，通过求两者在相同几何条件下比值的方式得出了衰减屏的透过率。提出采用多项式拟合插值的方式解决在轨角度密集的问题，计算可知拟合插值引入的不确定度优于0.04%。数据结果显示，衰减屏的平均透过率为13.3%，结果的总不确定性优于0.54%(覆盖因子k=2)。结果表明，该装置能够为太阳光衰减屏在轨使用提供数据支持。

Abstract

A set of measuring device for the transmittance of the solar attenuation screen is introduced. Two set of data are required: light signals transmitted through the test fixture with and without the solar attenuation screen. Then the solar attenuation screen transmittance is the ratio of the screen-on data to the screen-off data under the same geometric condition. The method of polynomial fitting interpolation is proposed, which is used to solve the problem of dense on-orbit angle. The error of the method is less than 0.04%. The results show that the average transmittance of the solar attenuation screen is 13.3%, and the uncertainty of the device is better than 0.54% (covering factor k=2). The results indicate that the device can provide data support for the use of the solar attenuation screen on orbit.
