We propose a compact polarization-resolved common-path digital holography for measuring the polarization distribution of a light field dynamically with high temporal stability. The designed experimental setup allows simultaneously recording, in a common-path manner, two holograms carrying the complex amplitude information of two orthogonal polarization components of the light field. Based on the theory of the Pancharatnam–Berry phase to retrieve the full Stokes parameters of the light field, we demonstrate the experiments with polarized optical elements, stressed glass plate, and micrometer-sized liquid crystal droplet. The measurement results verify the method’s high accuracy and stability, and the capability of measuring light fields with sizes ranging from centimeters to micrometers. Owing to the stable and compact optical path structure, this method is conducive to instrumentation and is expected to find wide applications in many fields.

基于 Pancharatnam-Berry 相位的紧凑型偏振分辨共径数字全息术

我们提出了一种紧凑的偏振分辨共路径数字全息术，用于以高时间稳定性动态测量光场的偏振分布。设计的实验装置允许以公共路径的方式同时记录两个全息图，这些全息图携带光场的两个正交偏振分量的复振幅信息。基于 Pancharatnam-Berry 相理论来检索光场的完整斯托克斯参数，我们展示了偏振光学元件、应力玻璃板和微米级液晶液滴的实验。测量结果验证了该方法的高精度和稳定性，以及测量从厘米到微米大小的光场的能力。由于稳定紧凑的光路结构，
