摘要
本文分析了薄型CCD用于大色散光谱观测时干涉条纹产生的原因,特征.给出了消除干涉条纹的方法以及以10830为中心波长处的太阳、恒星光谱的实测处理结果.
The CCD, used in a spectrophotometric mode, shows the usual optical interference effects caused by the near-monochromatic light and variations in thickness of the thinned CCD. These interference patterns are different at different wavelengths. When it is used to observe higher dispersion spctra at redder wavelengths, the fringe amplitude can be as high as observed stellar or solar spectral amplitude. The method eliminating interference fringe is given in this paper. The solar 10830(?) result observed and reduced is showed in this present article.
