摘要
En 中文
定量相位成像(QPI)是一种用于非侵入式、无标记表征透明样本的有价值技术,可获取折射率、厚度等参数。在多种QPI方法中,基于强度传递方程的算法因其非干涉实现方式及与部分相干照明的兼容性而具有吸引力。然而,传统的有限差分和多项式拟合技术常涉及空间分辨率与抗噪性之间的权衡,且需要顺序采集离焦强度分布。本研究提出了一种基于空间频率调制和相位传递函数(PTF)分析的单一快门QPI方法。可同时捕获多个离焦强度分布,并通过PTF选择离焦距离,无需样本或系统先验知识即可实现精确相位重建。实验结果表明,所提方法在相位重建质量方面优于传统单一快门QPI技术。(c) 2025 Optica Publishing Group under the terms of the Optica Open Access Publishing Agreement
