提出了一种基于空分复用技术的并行相移数字全息显微镜(PPSDHM)，它具有三维运动测量的能力。利用PPSDHM，可以在单次曝光的情况下同时获得样品的三维结构和相分布的瞬时信息。我们构建了一台平行相移数字全息显微镜，它由光学干涉仪和图像传感器组成，图像传感器上逐个像素地安装微偏振器。通过演示所构建的显微镜的单次激发三维成像和位相成像能力，验证了PPSDHM的有效性。
We propose parallel phase-shifting digital holographic microscopy (PPSDHM) which has the ability of three-dimensional (3-D) motion measurement using space-division multiplexing technique. By the PPSDHM, instantaneous information of both the 3-D structure and the phase distributions of specimens can be simultaneously acquired with a single-shot exposure. We constructed a parallel phase-shifting digital holographic microscope consisting of an optical interferometer and an image sensor on which micro polarizers are attached pixel by pixel. The validity of the PPSDHM was experimentally verified by demonstrating the single-shot 3-D imaging and phase-imaging ability of the constructed microscope.
