我们开发了一种分析模型,用于基于空间滤波的共路径干涉仪 (CPI) 的设计和优化。我们详细描述了数学分析,并展示了如何将其应用于优化一系列不同 CPI 的结果,从而开发出定量表征 CPI 表现的图形框架。对合成参考波中曲率的影响进行了详细的分析处理。我们证明,通过修改傅立叶滤波器可以提高某些标准干涉仪的线性度和条纹精度,并且我们提出并分析了双 CPI 系统,以在整个输入相位范围内实现相位到强度的明确映射。 (C) 2001 年美国光学学会 OCIS 代码:070.2580、070.6110、100.2650、100.5070、120.3180、120.5050。
We have developed an analytical model for the design and optimization of common-path interferometers (CPI's) based on spatial filtering. We describe the mathematical analysis in detail and show how its application to the optimization of a range of different CPI's results in the development of a graphical framework to characterize quantitatively CPI performance. A detailed analytical treatment of the effect of curvature in the synthetic reference wave is undertaken. We show that it is possible to improve the linearity and fringe accuracy of certain standard interferometers by a modification of the Fourier filter, and we propose and analyze a dual CPI system for the unambiguous mapping of phase to intensity over the complete input phase range.
