对干涉图分析中的子条纹积分法进行了研究和改进。本文介绍的改进算法，能够在存在噪声或载波频率误差的情况下重建相位。应用子条纹积分法分析了N桶积分法模拟的两种等间距斐索条纹图。并将其用于多光束斐索条纹的分析。用子条纹积分法和傅里叶变换法两种方法得到了聚乙烯光纤的折射率分布。使用保持的方法得到的结果之间的比较。
Some aspects concerning the subfringe integration method in interferogram analysis have been investigated and modified. The modified algorithm, introduced in this paper, is capable of reconstructing the phase in the presence of noise or errors in carrier frequency. The subfringe integration method was applied to analyze two computer simulated patterns of equispaced Fizeau fringes using N bucket integration. Also, it is used to analyze the multiple-beam Fizeau fringe. The refractive index profile of polyethylene fiber is obtained by using two methods, subfringe integration method, and Fourier transform method. A comparison between the obtained results using the maintained methods is presented.
