Maggi-Rubinowicz方法（MRM）是计算不透明平面物体衍射图样的有效工具。我们将MRM应用于平面矩形。在本研究的第一部分中，衍射图案之间的差异，无论是强度和相位分布，从一个倾斜的矩形和从正方形具有相同的正交投影在观察平面上，已被分析。在第二部分中，我们得到的MRM与角谱理论（AST）耦合到快速傅里叶变换（FFT）得到的结果进行了比较。这项工作的主要新奇在于，MRM特别适合于评估应用于AST-FFT计算的抗混叠程序。(C)根据OSA开放获取出版协议的条款，2019年美国光学学会
The Maggi-Rubinowicz method (MRM) is a useful tool to compute diffraction patterns from opaque planar objects. We adapted the MRM to planar rectangles. In the first part of this study, differences between diffraction patterns, both the intensity and the phase distributions, from a tilted rectangle and from the square having the same orthogonal projection on the observation plane, have been analyzed. In the second part, we compared results obtained with the MRM to those obtained with angular spectrum theory (AST) coupled to fast Fourier transform (FFT). The main novelty of this work is the fact that MRM is particularly well suited for evaluating anti-aliasing procedures applied to AST-FFT calculations.
