摘要

本文提出了一种处理具有二次相位差函数的两波干涉时条纹的数值方法。这种条纹的一个特殊例子是牛顿环。我们提出的数值方法是基于数据的离散菲涅耳(傅里叶)变换，它具有与最小二乘拟合(LSF)相同的精度。

Statistical processing of Newton's rings fringe pattern using the Fresnel transform

This paper presents a numerical method for processing the fringes obtained when two waves, with a quadratic phase difference function, interfere. As a particular case of this kind of fringes are the Newton's rings. The numerical method we present is based on the discrete Fresnel (Fourier) transform of the data and it has the same precision as the least square fitting (LSF).
