We propose single-shot digital holography which is capable of simultaneously capturing both the information of multiple phase-shifted holograms and the distribution of the polarization. In this technique, a single image sensor records both the information required for phase-shifting interferometry and that of the polarization states of objects using an array of polarizers. The essence of the technique is the capability of imaging the distribution of the polarization of three-dimensional objects with a single-shot exposure by using the space-division multiplexing of holograms. The validity of the proposed technique was confirmed by the preliminary experiments.
我们提出了一种能够同时捕获多个相移全息图信息和偏振分布的单次数字全息技术。在该技术中，单个图像传感器使用偏振器阵列记录相移干涉测量所需的信息以及物体的偏振状态的信息。该技术的本质是通过使用全息图的空间复用，以单次曝光的方式对三维物体的偏振分布进行成像的能力。通过初步实验验证了所提出技术的有效性。
