Abstract Divided-aperture (DA) microscopy is an imaging method that, in addition, improves the anti-scattering capability. The present state-of-the-art imaging methods have the drawbacks of requirement of scanning or low spatial resolution. In this paper, we propose a DA digital holographic microscopy (DADHM) to enable single shot quantitative phase imaging, which, to our knowledge, is the first-of-its-kind. The proposed system is built using a Linnik-type interferometric module associated with the DA technique. In this method, interestingly, an element tilt is not required to produce an off-axis angle between the sample and reference beams because of the employment of DA. Some analyses and experiments were conducted to validate the efficiency of the proposed method, and the results indicate that a high anti-scattering capability with a mean error of 2.42 nm were achieved by the proposed method.

具有分光孔径的离轴数字全息显微术

摘要 分割孔径（DA）显微镜是一种成像方法，此外，还提高了抗散射能力。目前最先进的成像方法具有扫描要求低或空间分辨率低的缺点。在本文中，我们提出了一种 DA 数字全息显微镜 (DADHM)，以实现单次定量相位成像，据我们所知，这是同类产品中的首创。所提出的系统是使用与 DA 技术相关的 Linnik 型干涉测量模块构建的。在这种方法中，有趣的是，由于采用了 DA，因此不需要元件倾斜即可在样品光束和参考光束之间产生离轴角。进行了一些分析和实验以验证所提出方法的有效性，
