Exploring the way to Correct the Error of Interferometer Using Binary Optical Phase Plate and Computer

摘要: 提出了一种利用二元光学位相板修正球面干涉仪误差的新方法,分别采用标量衍射理论和几何光学方法设计二元光学位相板,并且用计算机模拟修正结果,得到了令人满意的结果.同时,阐述了采用计算机图像处理技术修正干涉仪系统误差和检测球面镜的方法.

Abstract: The principle of using binary optical phase plate(BOPP)to correct the error of interferometer is proposed. BOPP is designed by diffraction theory and using geometrical optics. And the error correction for interferometer by means of computer image processing is presented. The feature of spherical mirror is examined.
