光干涉测量中影响恒星角距或角径测定精度的因素

Sources of Error Affecting the Measuring Accuracy of Stellar Angular Breadth in Optical Interferometry

在光干涉测量中,由于各种误差因素的影响,使得实际测量的条纹可见度比理论值小,从而使恒星角距或角径的测定产生系统误差。从理论上分析了几种主要的误差源对条纹可见度亦即对恒星角距或角径测定的影响情况,并给出了一种解决办法。

In optical interferometry, the measured fringe visibility is less than the truevalue due to errors, which results in systematic errors in the measurement of stellarangular breadth. Some main sources of error affecting the measurement of fringevisibility, hence stellar angular breadth, are analysed and a way to solve the prob-lems is shown in this paper.
