Measurement of surface shape and refractive index for moving transparent objects is critical in various fields. A parallel phase-shifting digital holography system that can record and reconstruct the phase information of moving transparent objects using two high-resolution polarization imaging cameras was presented. In the developed system, two polarization imaging cameras with 3.45 µm pixel pitch passed through the object in different directions. These two polarization imaging cameras were controlled by LabVIEW and worked synchronously. The proposed system can obtain the object's integral phase distributions in different directions, which is more effective for measuring an asymmetric object. In the experiment, the resolution of the system was confirmed by using a transmission-type test target. Besides, the dynamic phase measurement of an irregularly shaped transparent object was completed to verify the proposed system's effectiveness.

利用双偏振成像相机通过并行相移数字全息术动态测量透明物体的相位

在各个领域,测量移动透明物体的表面形状和折射率至关重要。提出了一种并行相移数字全息系统,该系统可以使用两个高分辨率偏振成像相机记录和重建移动透明物体的相位信息。在已开发的系统中,两个像素间距为3.45 µm的偏振成像相机以不同方向穿过物体。这两个偏振成像相机由LabVIEW控制并同步工作。所提出的系统可以获得物体在不同方向上的积分相位分布,这对于测量非对称物体更有效。在实验中,通过使用透射型测试目标确认了系统的分辨率。除了,
