A typical difficulty to display the Fresnel hologram in real time is calculation of huge information. In this paper, we propose a method to define the optimum size of segmentation for the Phase-Added Stereogram, which can generate high quality hologram rapidly, and describe a generation algorithm of the Phase-Added Stereogram using the Fast-Fourier Transform for fast calculation. Moreover, we have built an optical holographic display system for real-time holographic display to implement the proposed method. To generate the fringe pattern, we used 3D information, which is a set of the 3D points converted from a 3D model. Finally, the generated hologram is displayed on the optical holographic display system in real time. In consequence, we could achieved that digital hologram can be displayed at 15 frame/second with 1,000 object points.
