Abstract

The superimposing method for information reduction in hologram is compared with the sampling method to clarify their features. Visual field is divided in several fields for displaying visual depth of the image under reduced information, and partial images in divided visual fields are separately recorded on several Fourier transform holograms (FTHs). A time-sharing display system is developed to reconstruct the 3D image in real time from several FTHs. The 3D image with motion parallax is reproduced in the wide viewing zone from holograms with reduced information by reconstructing overlapped two images. Experiments are carried out for reconstruction of the practical 3D image from recorded holograms. Results show that resolution of the image is improved and the speckle noise is suppressed by the superimposing method. Depth of the 3D image can be perceived by viewing partial images reconstructed on Fourier transform planes. Observer can perceive motion parallax of the image by viewing a pair of overlapped stereoscopic images from right-eye and left-eye positions.
