    摘要: A holographic display system (100) for generating a super hologram (150) with full parallax in the horizontal and vertical directions. The system includes an array of holographic display devices (110), e.g., spatial light modulators (SLMs, 114), operable to provide a plurality of holographic images (115) of a scene from differing viewpoints of the scene. Each SLM is operated concurrently to output a narrow field of view, elemental hologram. The system includes coarse integral optics (120) combining the holographic images into a single hologram ("super hologram", 150) viewable in a hologram image plane a distance from the coarse integral optics. The coarse integral optics combine the holographic images by providing angular tiling of the holographic images, e.g., bending the axes (141) of parallel lenses. In this manner, the field of view, in one direction, of the super hologram is based on the number of holographic display devices provided in the array in one direction.

    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: A dynamic three-dimensional image can be modified in response to poses or gestures, such as hand gestures, from a user. In one implementation, the gestures are made by a user who selects objects in the three-dimensional image. The gestures can include indications such as pointing at a displayed object, for example, or placing a hand into the volume of space occupied by the three-dimensional image to grab one or more of the displayed objects. In response to the gestures, the three-dimensional display is partially or completely redrawn, for example by an alteration or repositioning of the selected objects. In one implementation, a system simulates the dragging of a displayed three-dimensional object by a user who grabs and moves that object.
