摘要研究子孔径拼接在长平晶测试中的应用。讨论子孔径拼接的基本原理,建立了子孔径拼接模型,确定了进行长平晶拼接测试的基本算法。根据最小二乘法的基本原理,编制了子孔径拼接数据处理程序。
论文首先对长平晶做了简单的介绍,然后详细阐述了子孔径拼接的原理以及拼接的各种方式,再结合长平晶的特点选择100mm口径移相干涉仪来进行检测,采用圆形子孔径的一文平行排列方式,拼接方式采用串行拼接,对于210mm长平晶只需3个子孔径串行拼接,而310mm长平晶则需要4个子孔径串行拼接。之后根据最小二乘法原理,编制了子孔径拼接程序。最后结合已有的实验结果说明子孔径拼接检测长平晶这种方法的可行性。9382

Title The application research in long optical flat testing
Abstract
The study sub-aperture stitching in the long optical flat test. Discuss the basic principles for the stitching, the establishment of sub-aperture stitching model to determine the long optical flat stitching test of the basic algorithm. According to the basic principles of the least squares method, the preparation of the sub-aperture stitching data handler.
Firstly, the long optical flat with a brief introduction, then elaborated the principle of the stitching and the stitching of a variety of ways, combined with the long optical flat characteristics to choose the 100mm caliber phase-shifting interferometer to detect, using a circular sub-aperture parallel to the one-dimensional arrangement of splicing using serial splicing, only three sub-aperture serial stitching, 310mm long flat crystal 4 sub-aperture serial splicing 210mm long flat crystal. After the least squares method, the preparation of a sub-aperture stitching program. Finally predecessors have done experiments stitching detect long flat crystal of this method to make accurate assessment.
Keywords sub-aperture stitching long optical flat measurement image processing
