提出了一种基于Wollaston棱镜的快拍相移衍射相位显微镜（WP-SPYD），用于低相干快拍定量相位成像和摄像。沃拉斯顿棱镜以足够小的分离角分离两个具有高偏振度的正交线偏振光束;其中一个光束通过针孔作为参考光束。利用偏振相机同时获取四幅相移干涉图，以精确地获取高空间分辨率的相位图。该系统几乎是共路配置，可以实现大斜率范围和高精度。除了抗环境噪声的能力外，WP-SPTORIC还适用于使用低相干光的相位测量。该系统的精度和大的可测量的斜率范围进行了验证，并与商业轮廓仪进行了实验比较。我们认为，WP-SPIRED是一种强有力的工具，用于精确和鲁棒的定量相位测量，并具有显着的潜力的实时相位成像。
We proposed a Wollaston-prism-based snapshot phase-shifting diffraction phase microscope (WP-SPDPM) for low-coherence snapshot quantitative phase imaging and videography. Wollaston prism separates two orthogonally linearly polarized beams with high degrees of polarization at a sufficiently small separation angle; one of the beams passing through a pinhole serves as the reference beam. Four phase-shifted interferograms are simultaneously acquired with a polarization camera to accurately retrieve a high spatial resolution phase map. The system is nearly common-path in configuration and can achieve a large slope range and high accuracy. In addition to the ability to resist environmental noise, the WP-SPDPM is suitable for phase measurement using low-coherence light. The accuracy and large measurable slope range of the proposed system is validated and compared experimentally with a commercial profilometer. We believe WP-SPDPM is a powerful tool for the accurate and robust quantitative phase measurement and has a significant potential of the real-time phase imaging.
