Paper Abstract

The holographic stereogram approach is used to reduce computational time of computer- generated hologram for 3D displays. It can be obtained by Fourier transforms of an array of 2D perspective images, and computational speed is quite faster than that of Fresnel hologram. However, the conventional holographic stereograms are made from an array of pure 2D perspective images, which do not have depth information. Therefore, the reconstructed 3D image has lower resolution than that of Fresnel hologram. In this paper, we have discussed the stereographic approach as an approximation of wavefront reconstruction, and propose `integral hologram' which can be defined as an improved or `coherent' stereogram. `Integral hologram' is calculated by a similar way to the holographic stereogram. However, the input data are obtained not from an array of 2D perspective images, but from 3D coordinates of the object. From numerical analysis, we demonstrate that the `integral hologram' has image resolution as high as Fresnel hologram, and can be computed as fast as the conventional holographic stereogram.
