摘要： A method of computing a hologram by determining the wavefronts at the approximate observer eye (OE) position that would be generated by a real version of an object to be reconstructed. In normal computer generated holograms, one determines the wavefronts needed to reconstruct an object; this is not done directly in the present invention. Instead, one determines the wavefronts at an observer window (OW) that would be generated by a real object located at the same position of the reconstructed object (3D-S). One can then back-transform these wavefronts to the hologram to determine how the hologram needs to be encoded to generate these wavefronts. A suitably encoded hologram (HA) can then generate a reconstruction of the three-dimensional scene (3D-S) that can be observed by placing one's eyes at the plane (OP) of the observer window (OW) and looking through the observer window (OW).

摘要： Die Erfindung betrifft eine Einrichtung zur Rekonstruktion einer dreidimensionalen Szene mit einem optischen System, enthaltend mindestens eine reelle oder virtuelle punkt- oder linienförmige, hinreichend kohärente Lichtquelle (1) und eine Linse (2), sowie mit einem steuerbaren Display (3) aus matrixförmig oder in anderer Weise regulär angeordneten Zellen mit mindestens einer in Amplitude und/oder Phase steuerbaren Öffnung je Zelle. 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： A holographic display including light sources (LS1, LS2, . . . ) in a 2D light source array, lenses (L1, L2, . . . ) in a 2D lens array, a spatial light modulator (SLM) and a beamsplitter, in which there are m light sources per lens, and the light sources are in m-to-one correspondence with the lenses. The beamsplitter splits the rays leaving the SLM into two bundles, one of which illuminates the virtual observer windows for m left eyes and the other illuminates the virtual observer windows for m right eyes. In one example, m=1. An advantage is 2D-encoding with vertical and horizontal focusing and vertical and horizontal motion parallax.

摘要： A holographic display device (910) comprises a first OLED array (91, 92) writing onto a first OASLM (95-98), the first OLED array and the first OASLM forming adjacent layers, and a second OLED array (906, 907) writing onto a second OASLM (901, 903), the second OLED array and the second OASLM forming adjacent layers. The first and the second OASLMs encode a hologram and a holographic reconstruction is generated by the device when an array of read beams (909) illuminates the first and second OASLMs and the first and second OASLMs are suitably controlled by the first and second OLED arrays. Advantages include that this device permits independent control of phase and amplitude, and the device lends itself to compactness.

摘要： A mobile telephony system comprising a calling party mobile telephone with an imaging system and a display. The imaging system is operable to capture an image of the calling party. The calling party mobile telephone sends an image of the calling party to a called party mobile telephone over a wireless link, and the called party mobile telephone locally generates a holographic reconstruction of the calling party using a holographic display that is encoded with a hologram. An advantage is that a mobile telephone call may be held in which one party views a holographic reconstruction of the other party.

摘要： The invention relates to a projection device (1) for the holographic reconstruction of scenes, said projection device comprising at least one light modulation device (2, 2R, 2G, 2B) and at least one light source (4) having a sufficient amount of coherent light for generating a wavefront (8, 8R, 8G, 8B, 8L) of a scene, encoded in the light modulation device. Reproduction means (6) are used to reproduce a Fourier transformation (FT) of the light from the light source (4), modulated by the light modulation device (2, 2R, 2G, 2B), onto a screen (7). In the same way, the wavefront (8, 8R, 8G, 8B, 8L) encoded on the light modulation device (2, 2R, 2G, 2B) is represented by means of the reproduction means (6) in at least one virtual observation window (11, 11R, 11L, 24R, 24L, 28R, 28L) of an observation plane (12). In order to pan the observation window (11, 11R, 11L, 24R, 24L, 28R, 28L) according to a change in the eye position of at least one observer, at least one deflection means (18) is arranged between the light modulation device (2, 2R, 2G, 2B) and the screen (7).

摘要： A reconfigurable, three-dimensional display (1) wherein knowledge of the viewer's (4) eyes is used to enable the effective exit pupil(s) of the display system to be optimised. The system utilises this knowledge to identify contributing regions (5) within the display (1) that contribute light to the viewer (4). Priority is given to calculating and displaying the part of the display corresponding to the contributing region (5), thereby allowing the system computation requirements to be minimised. Further computation savings are achievable by recognising that only light travelling in a limited range of angles need to be considered.
