摘要： The invention relates to a process by which a multi-image type hologram wherein one 3D image changes over to another depending on a viewing direction can be fabricated in simple construction and a multi-image type hologram fabricated by that process. According to the process for the fabrication of a multi-image type hologram wherein one image changes over to another depending on a viewing direction, the area of a hologram recording material is divided into a plurality of sub-areas 111, 112 and 113. Objects to be displayed on different images are holo-graphically recorded in the respective sub-areas, using reference light having the same angle of incidence, thereby recording the first-stage hologram 11. Object images O1′, O2′ and O3′ recorded in the respective sub-areas 111, 112 and 113 are simultaneously reconstructed from the recorded first-stage hologram 11, so that a second-stage hologram recording material 21 is located near the reconstructed object images O1′, O2′ and O3′ for recording them as a reflection or transmission type volume hologram.

摘要： Arrangements are made to enable different original images to be reproduced upon observation from different positions and yet enable reproduced images of high resolution to be obtained. In a case of recording two original images, each of the two original images Ia and Ib is defined as a set of point light sources in an XYZ global coordinate system, and two propagation spaces Sa and Sb, each enabling propagation of light emitted from an origin Q of an αβγ local coordinate system, are defined. A predetermined recording plane and a reference light are set in the XYZ coordinate system, and an interference fringe pattern, which is formed on the recording plane by object light components from the point light sources constituting the respective original images and the reference light, is determined by computation. In this process, the computation is performed upon deeming that a light from a point light source belonging to the original image Ia spreads only within the propagation space Sa, with the origin Q of the αβγ coordinate system being overlappingly set at the position of the point light source, and that a light from a point light source belonging to the original image Ib spreads only within the propagation space Sb, with the origin Q of the αβγ coordinate system being overlappingly set at the position of the point light source.

摘要： The invention relates to a computer-generated hologram that is capable of reconstructing a full-color image and achieving a resolution higher than ever before. The recording plane 20 of the hologram is divided by a multiplicity of parallel sections in the horizontal direction to define a multiplicity of areas C1r, C1g, C1b, etc. Amplitude information and phase information corresponding to periodically different wavelengths RGB are recorded in a direction traversing the multiplicity of areas. Upon reconstruction by given illumination Lw, reconstructing light having periodically different wavelengths diffracted from the amplitude information and phase information recorded in the respective areas travels toward the recording plane of the hologram such that the reconstructed image can be viewed at a point-of-view position that is a given position E. Information about the same portion of the original image is recorded in individual points belonging to the same area, and information about another corresponding portion of the original image is recorded in individual points belonging to another area.
