In das steuerbare Display (3) ist ein Videohologramm kodierbar. Die Linse (2) erzeugt ein Bild der Lichtquelle (1) in einer Betrachterebene (4). In der Betrachterebene (4) ist ein Betrachterfenster (5) innerhalb einer Beugungsordnung des steuerbaren Displays (3) lokalisierbar. Durch das Betrachterfenster (5) hindurch ist die dreidimensionale Szene (6) betrachtbar, wenn ein Auge eines Betrachters an dem Betrachterfenster (5) positioniert ist. Das Videohologramm enthält ein Gebiet mit Information, die benötigt wird, um einen einzelnen Punkt (7) in der dreidimensionalen Szene (6) zu rekonstruieren, der vom Betrachterfenster (5) aus sichtbar ist. In dem Gebiet ist Information für diesen einzelnen Punkt (7) in der rekonstruierten dreidimensionalen Szene (6) kodierbar. Dieses Gebiet ist das einzige Gebiet im Videohologramm, das mit Information für diesen Punkt (7) kodierbar ist. Dieses Gebiet ist in der Größe so begrenzt, dass es einen Teil des gesamten Videohologramms bildet, wobei die Größe so bemessen ist, dass keine durch höhere Beugungsordnungen verursachten mehrfachen Rekonstruktionen dieses Punktes (7) vom Betrachterfenster (5) aus zu sehen sind.

摘要： The device has an optical system with a light source(s) and lens. The video hologram has cells, e.g. in a matrix, with an opening(s) per cell of controlled amplitude/phase and an observation plane. An observation window in the observation plane at a periodicity interval of the reconstruction as a Fourier transform of the video hologram enables viewing of a three-dimensional scene. The window size is not greater than the periodicity interval. The device has an optical system consisting of at least one real or virtual point- and/or line-shaped, adequately coherent light source (1) and a lens (2) and the video hologram (3) consists of cells in a matrix or other regular arrangement with at least one opening per cell of controlled amplitude and/or phase and an observation plane at the location of the light source image. An observation window (5) is located in the observation plane at a periodicity interval of the reconstruction as a Fourier transform of the video hologram for observation of a three-dimensional scene (6). The size of the window is not greater than the periodicity interval.

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.

摘要： System and method for video holographic display. Information is received regarding a 2D hogel array with multiple hogel apertures, specifying number, size, and/or spacing of the hogel apertures. Information regarding a 3D scene is received, including a scaling factor mapping the 3D scene to a 3D display volume. Due to gradual variation of radiation patterns from hogel to hogel, a full set of color radiation intensity patterns for the entire hogel array may be generated by interpolating the color radiation intensity patterns from a sparse subset of the hogels without having to compute all of the patterns. The full set of color radiation intensity patterns may then be used to holographically display the 3D scene.

摘要： A hologram that can obtain high diffraction efficiency when reconstructed and is superior in productivity is provided. An arbitrary object image and a recording surface in which representative points are disposed with predetermined pitches are defined by use of a computer. At the position of each individual representative point, a complex amplitude for the wave front of object light emitted from the object image is calculated, and a complex amplitude distribution is calculated on the recording surface. This complex amplitude distribution is expressed by a three-dimensional cell having a groove in the surface thereof. Four kinds of groove depths are defined in accordance with the phase θ , and seven kinds of groove widths are defined in accordance with the amplitude A. Thereby, 28 kinds of three-dimensional cells in total are prepared, and a three-dimensional cell corresponding to the phase θ and amplitude A of the complex amplitude for the representative point is disposed at the position of each representative point. One of the 28 kinds of three-dimensional cells is disposed at the position of each representative point on the recording surface, and thereby a hologram-recording medium is formed as a set of three-dimensional cells. A reconstructed image is obtained by the phase/amplitude modulating function of the groove part of each cell.

摘要： A three-dimensional imaging system is described which exploits the defocusing of non-zero diffraction order images caused by the quadratic distortion of a diffraction grating (4). An optical system (1) is used such that objects (5, 6 and 7), located at different distances from grating (4), are imaged simultaneously and spatially separated on a single plane B.
