Abstract

The superimposing method is described in order to reduce information in hologram. This method improves loss of resolution and increase of the speckle noise due to the information reduction as compared with the sampling method. Experiments are carried out for reconstruction of images from the computer-generated hologram or from the practical hologram. Results show that high-resolution images with low speckle noise are reconstructed from the continuous periodic hologram with reduced information. The image having no parallax is reconstructed on the Fourier transform plane from the hologram with reduced information, if the bandwidth is taken to be smaller than the diameter of observer’s pupil. A time-sharing system is developed in order to display real-time 3D images with full parallax using several Fourier transform holograms with reduced information.
