论文摘要

从光条纹模式中检索对象阶段是定量相成像中的一项关键任务,通常需要适当的图像预处理(背景和噪声最小化),尤其是当从单弹条边缘模式图像中检索阶段时。在本文中,我们首次提议适应2D快速迭代过滤(FIF)用于条纹模式分解的方法,并开发了FIF的新颖版本,称为2D流纹模式快速迭代过滤(FPFIF2),该版本是针对条纹模式预处理量身定制的。与前2d FIF实现有关处理速度,质量和使用舒适性的实施相比,我们显示了FPFIF2对边缘模式过滤的积极影响。我们还将FPFIF2与其他最先进的条纹模式过滤方法进行了比较,以帮助希尔伯特螺旋变换方法在相位检索中。使用数值模拟和实验条纹分析,我们证明FPFIF2优于参考方法,尤其是在低fring-Fringe-Contrast相相重建质量和分解时间方面。

Retrieving object phase from the optical fringe pattern is a critical task in quantitative phase imaging and often requires appropriate image preprocessing (background and noise minimization), especially when retrieving phase from the single-shot fringe pattern image. In this article, for the first time, we propose to adapt the 2D Fast Iterative Filtering (FIF) method for fringe pattern decomposition and develop a novel version of FIF called the 2D fringe pattern Fast Iterative Filtering (fpFIF2), that is tailored for fringe pattern preprocessing. We show the positive influence of fpFIF2 onto fringe pattern filtering comparing to the previous 2D FIF implementation regarding processing speed, quality, and usage comfortability. We also compare the fpFIF2 with other state-of-the-art fringe pattern filtering methods in terms of aiding the Hilbert spiral transform method in phase retrieval. Employing numerical simulations and experimental fringe analysis, we prove that fpFIF2 outperforms reference methods, especially in terms of low-fringe-contrast phase reconstruction quality and decomposition time.
