One-step holographic stereograms which can reconstruct large images have been produced by an extremely anamorphic optical system. One of the important lenses is the long and narrow cylindrical lens with small f-number. The lens is designed as a composite dual lens. Reference light is illuminated through this composite lens and the special configuration with cylindrical lenses is considered. But in the one-step holographic stereogram, if the series of conventional perspective original images are used without performing any anamorphic image processing, the reconstructed images are observed behind the hologram plane. In order to enhance the sense of perspective of the reconstructed images and minimize blur of the reconstructed image, an image processing technique is introduced. In this report, the authors describe their optical system and the image processing technique which can display a large and bright 3D image, with about 55 degree(s) viewing zone.
