Abstract
The reality of 3D image is highly influenced by the screen size. The authors developed a large hologram screen for providing 3D image like natural scenery. The screen can display bright and clear image because the hologram is one focus type. The number of view points can be arbitrarily varied only by changing the number of 2D images projected from an LCD projector. The screen is available to any projected color because the hologram is overall achromatized in the vertical direction. It will be easily enlarged by arranging several holograms like a multi-vision TV.
