平行相移数字全息术是一种数字全息技术，擅长对运动物体进行高速记录。该技术可以从记录的全息图中计算出物体的位相分布，因此在高速三维测量中得到了积极的应用。在本文中，我们回顾了由高速偏振成像相机(FASTCAM-SA5-P，Photoron，Inc.)组成的高速并行相移数字全息系统。波长532 nm，输出功率150 mW的Nd：YVO4激光器。在实验中，为快速物体设置了简单的放电装置，分别以25000fps和100万fps的速度成功地记录了放电现象。
Parallel phase-shifting digital holography is one of digital holographic techniques and good at high-speed recording of moving object. The phase distribution of the object can be calculated from recorded hologram so that the technique has been actively applied in high-speed three-dimensional measurement. In this paper, we review a high-speed parallel phase-shifting digital holography system consists of a high-speed polarization-imaging camera (FASTCAM-SA5-P, Photoron, Inc.) and a Nd:YVO4laser with 532 nm wavelength, 150 mW output power. In the experiment, a simple electrical discharging equipment was set for the fast object, and the electrical discharging phenomenon was successfully recorded at the rate of 25,000 fps, and 1,000,000 fps respectively.
