摘要： A stereoscopic display method whereby a hologram phase distribution is calculated and the calculated phase distribution is converted into a wave front of the light, thereby displaying a solid image. Further, a feature portion in a display target specified by 3-dimensional information is detected. Sampling points are set at a high density into the detected feature portion. Sampling points are set at a low density with respect to a non-feature portion as a portion other than the feature portion. In the phase calculation, a hologram phase distribution is calculated with respect to the set sampling points.

摘要： Des objets traités par ordinateur ou créés par ordinateur peuvent être utilisés pour construire des hologrammes (10) dont les images sont proches d'une surface d'hologramme (10) ou enjambent celle-ci. Le procédé ne requiert pas d'hologramme initial ou préliminaire. L'hologramme (10) est constitué d'un certain nombre de petites parties élémentaires et contiguës (12). Des perspectives inhabituelles, de l'intérieur de l'objet (30), sont requises pour la création de ces éléments (12). Un procédé de génération de ces perspectives consiste à utiliser des manipultions uniques d'objets. Les transformations par calcul assurent au'aucune singularité n'est produite, et des programmes de modélisation et de représentation plus ou moins classiques peuvent être utilisés. Selon un second procédé, une multiplicité de perspectives d'objet classiques peut être rassemblée. Tous les pixels (22) dans ces plans d'image classiques (20) sont alors réaffectés à de nouveaux emplacements différents dans les nouveaux plans d'image (20) afin d'obtenir des perpsectives élémentaires (22). Ces procédés peuvent être utilisés pour construire des hologrammes arc-en-ciel ou des hologrammes à parallaxe intégral. Lorsque ces procédés sont correctement exécutés, les hologrammes ne peuvent pas être distingués visuellement des autres types d'hologramme.

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

摘要： Methods for generating holograms from a computer model of any object (30) employ a combination of numerical and optical means. An illumination model and the light dispersion properties of the object (30) are specified. The hologram (50) is synthesized from a plurality of smaller hologram elements (52, 54). Each individual element (52, 54) sustains a field of view of the object. The light rays from the object lying within the field of view and along the lines of sight are sampled by the computer (60). The sample density should not exceed the resolution limit set by the size of the hologram element (50). Each light ray is specified by a direction and an amplitude function. The hologram element (52, 54) is obtainable from a Fourier Transform of the sampled rays. In one embodiment, optical means are employed to physically reproduce the sampled light rays using coherent radiation. The reproduced coherent light rays are then interfered with a coherent reference beam to form the hologram element (52, 54). Alternatively, the interference pattern is calculated directly by the computer (60) and is printed to form the hologram element (52, 54).

摘要： Light emitted from a coherent light source (10) undergoes fine adjustment of its polarizing direction by a polarizing device (40) and is directed to a liquid crystal device (1) through a collimating optical system (20,23,21). The polarizing device (40) is capable of fine-adjusting the polarizing direction in accordance with the wavelength of the incident light, thereby providing a high contrast ratio. When an image is recorded by holography using such a liquid crystal spacial light modulator, it is possible to obtain an image of high quality.

摘要： Procédés de production d'hologrammes à partir d'un modèle informatique d'un objet quelconque (30), utilisant des moyens optiques et numériqus combinés. On spécifie un modèle d'éclairage et les propriétés de dispersion de la lumière de l'objet (30). L'hologramme (50) est synthétisé à partir d'un ensemble d'éléments holographiques plus petits (52, 54). Chaque élément individuel (52, 54) supporte un champ de vision de l'objet. Les rayons lumineux provenant de l'objet situé dans le champ de vision et le long des lignes de vision sont échantillonnés par l'ordinateur (60). La densité d'échantillonnage ne devrait pas dépasser la limite de résolution déterminée par la taille de l'élément holographique (50). Chaque rayon lumineux est spécifié par une direction et par une fonction de l'amplitude. On peut obtenir l'élément holographique (52, 54) à partir d'une transformée de Fourier des rayons échantillonnés en utilisant une radiation cohérente. On provoque ensuite l'interférence des rayons de lumière cohérente reproduits avec un faisceau cohérent de référence, de manière à former l'élément holographique (52, 54). Dans une variante, la frange d'interférence est calculée directement par l'ordinateur (60) et imprimée pour former l'élément holographique (52, 54).

摘要： A holographic three-dimensional display system and a holographic three-dimensional display method are disclosed. Plane pixel information (J*K*M*N) of the flat panel display is reasonably used to convert the discrete spatial spectrum image information I mn into the discrete spatial spectrum image S jk by using holographic coding conversion, the discrete spatial spectrum thereof is restored by using corresponding lens arrays, and the discrete spectrum widening of the sampling angle É mn is realized by the holographic function screen so as to realize complete spatial spectrum restoring of an original three-dimensional space. By using the lens arrays and the holographic function screen, an inherent conflict between the imaging quality of a microlens array and the resolution of a displayed three-dimensional image in integration photography is effectively overcome, and eye visible perfect true three-dimensional display is realized, thereby obtaining eye visible prefect true three-dimensional display.
