摘要： A hologram of a virtual object or an object which actually exists is formed and a solid image is displayed. 3-dimensional information of the object to be displayed is divided into regions in the depth direction. Depth images are formed as 2-dimensional images where are seen from a plurality of points which are obtained by finely dividing the hologram forming surface for every region. A phase distribution at the hologram forming surface is calculated from the depth images and displayed on a liquid crystal display or the like as an electronic hologram. A reference light is irradiated onto the display and is converted into an optical wave front, thereby displaying a solid image. When forming a hologram recording medium, a zone image corresponding to each of the finely divided exposure regions of a dry plate is exposed multiple times.

摘要： A holographic display system for generating a super hologram with full parallax in different fields of view in the horizontal and vertical directions. The display system includes assemblies or subsystems each adapted to combine holographic displays and coarse integral displays to produce or display a coarse integral hologram. Briefly, the display system described herein teaches techniques for enhancing operations of coarse integral holographic (CIH) displays. The enhanced CIH displays may utilize ganged scanners, may operate scanners to provide boustrophedon scanning, may be configured to add color information such by view sequential color hologram display and scanning, may replace or supplement X-Y scanning abilities with a resonant scanner, and may replace physical lenslet arrays by generating and displaying a holographic lenslet for each elemental hologram used to create the super hologram.

摘要： The invention relates to a method for generating video holograms for a holographic reproduction device with at least one light modulation means, wherein a scene split into object points is encoded as a whole hologram and can be seen as a reconstruction from a visibility region, which is located within a periodicity interval of the reconstruction of the video hologram. The visibility region, together with each object point of the scene to be reconstructed, defines a subhologram and the whole hologram is generated from a superposition of subholograms, wherein in a sequence of image contents the difference subholograms of object points are preferably generated for each picture, differing in regards to the visibility according to the viewer position in sequential images of the sequence. The display device comprises means that provide high-quality video holograms in spite of the data amount being significantly reduced.

摘要： The invention relates to a computer-generated hologram fabrication process that can reduce loads on computation of interference fringes for an original image including micro-characters. A visually perceivable original image 11 and a visually unperceivable original image 12 (micro-characters) are defined, and sample point sources of light P are defined at a low density on the original image 11 and at a high density on the original image 12. Interference fringes of object light coming from the point light sources on the original image 11 and reference light R are found on each computation point within an area α1 on a recording surface 20, and interference fringes of object light coming from point light sources on the original image 12 and reference light R are found on each computation point within an area α2 on the recording surface 20. The light sources that become samples are defined at a given pitch on sectional lines obtained by cutting the original images 11 and 12 by a multiplicity of sections (parallel with an XZ plane) located at a given spacing. The section-to-section spacing for the original image 12 is made narrows than that for the original image 11.
