The strong need in materials and biological science has prompted the development of high-speed quantitative phase imaging. However, for phase retrieval applying digital micromirror devices (DMDs), the accuracy of the retrieved phase will be disturbed by the DMD-induced aberrations. Here, we propose a phase retrieval method based on measuring and correcting errors caused by phase non-uniformity of the device. Using only four binary amplitude masks and corresponding diffraction intensities, the proposed method achieves rapid convergence and high-quality reconstruction. The experiments prove the practical feasibility for general samples and the effective improvement of the retrieved phase accuracy.

基于数字微镜设备的波前校正的定量相位成像。

材料和生物科学的强烈需求促使高速定量相成像技术的发展。但是，对于使用数字微镜设备（DMD）的相位检索，DMD引起的像差会干扰所检索相位的准确性。这里，我们提出一种基于测量和校正由设备的相位不均匀性引起的误差的相位检索方法。该方法仅使用四个二进制振幅掩模和相应的衍射强度，即可实现快速收敛和高质量重构。实验证明，该方法适用于一般样品，有效地提高了提取的相位精度。
