反射式单星模拟器光纤耦合光源设计

为了满足星敏感器地面标定及配合多个单星模拟器使用要求，针对传统星模拟器光源的特点，设计了一种积分球与多光纤耦合的模拟器光源，每一单星模拟器星点亮度由每一路耦合光束控制。根据指标要求，在光度学角度上对能量进行分析，并确定光源、积分球以及光纤的选取。利用Light tools 建立仿真模型，分析仿真结果，最终结果表明该光纤耦合光源满足设计要求，每个星点用Light tools 模拟照度误差与实际模拟照度误差相近且两者均不大于±10%。

Abstract

In order to meet the requirements of ground calibration of star sensor and assorted usage with single star simulators, a light source coupled by integrating sphere and multiple optical fibers is designed based on the characteristics of conventional light source of star simulators. The luminance of each single star emitted by star simulation is controlled by each coupled beam. According to the requirements of indicators, the types of light source, integrating sphere and optical fiber can be confirmed by analyzing the energy in perspective of photometry. Using simulation model established by Light tools and analyzing the simulation results, it is found that the fiber-coupled light source meets the design requirements, and the illumination simulation error of each magnitude is similar to the practical illumination error and both of them are not more than ±10%.
