In this paper, we report a common-path, phase-shift optical microscope based on measurement of Stokes parameters and to extract the three-dimensional (3D) phase map of transparent objects with high precision. The microscope employs three polarizers and two identical quarter-wave plates to extract and . The reference phase in the absence of the object is subtracted from the total phase in the presence of the object to extract the 3D phase of the object. The microscope is tested on imaging a USAF resolution test target and a reticle test pattern with excellent results. To the best of our knowledge, this is the first report of a common-path phase-shift optical microscope for 3D phase extraction based on measurement of Stokes parameters and .
在本文中，我们报道了一种基于斯托克斯参数测量的共光路相移光学显微镜，用于高精度提取透明物体的三维（3D）相位图。该显微镜采用三个偏振器和两个相同的四分之一波片来提取和。在有物体存在时的总相位中减去无物体时的参考相位，以提取物体的3D相位。该显微镜对美国空军分辨率测试靶标和标线片测试图案进行成像测试，结果优异。据我们所知，这是基于斯托克斯参数测量用于3D相位提取的共光路相移光学显微镜的首次报道。
