IMAGE RECORDING APPARATUS AND METHOD

摘要

To produce a rainbow-type holographic stereogram, an object beam is focused in the vertical direction with a cylindrical Fresnel lens. On the other hand, according to the edge-lit scheme, a reference beam is applied to a hologram recording medium via a light introduction block. A color holographic stereogram can be produced by utilizing a phenomenon that the color of a reproduction image is varied by moving the cylindrical Fresnel lens by a proper distance in the vertical direction.
