星敏感器单星模拟光源系统

Light Source System for Simulating Single Star Used in Calibration of Star Sensor

在星敏感器的标定检测中 ,通常要求提供一个模拟星 ,以便在实验室内标定星敏感器 ,从而减少大气变化的影响。模拟星的设备通常称为星模拟器 ,它们提供相对被测物体无限远的点光源作为模拟星 ,对其大小、光度 (星等值 )、光谱特性、色温类型等进行严格模拟。对实现模拟单星的研究作了详细的介绍。

In the calibration and checking of star sensor,a simulated star is required to provide.In this way the star sensor can be calibrated in the laboratory and the effect of atmospheric variation can be reduced.The equipment for simulating stars usually are called star simulators.The star simulators provide point sources infinite far relative to the measured objects as the simulated stars. Their sizes,luminosity (star magnitude) ,spectral property and colour temperature will be strictly simulated.The study on simulating single star is introduced in detail.
