The key point is study the interference pattern of sub-mirrors and the wavefront and draw conclusion in the field of physical optics to get the trait and date of the misadjustment. 研究重点是通过对子镜的干涉图和波前判研以及对系统的物理光学分析获得失调特征和数据,从而指导装调。
We propose a novel method to obtain speckle fringe patterns of ESPI from undeformed and deformed speckle patterns. 本文基于变形前和变形后的散斑图,提出一种获得电子散斑干涉条纹图的新颖方法。
The results show that this technique is capable of significantly improving the quality of fringe patterns.It works well as a pre-processing for the fringe patterns by ESPI. 结果表明该技术能够显著改善条纹图的质量,是一种行之有效的电子散斑干涉条纹图的预处理方法。
