Paper Abstract

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:YVO4 laser 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.
