| 20090303314 | Direction-Controlled Illumination Unit for an Autostereoscopic Display - A direction-controlled illumination unit for an autostereoscopic display, which unit deflects light from activated illumination elements through a transmissive image reproduction means in the space in front of the display into visibility areas, from which a stereoscopic and/or monoscopic representation can be seen. The direction-controlled illumination unit contains an illumination means having illumination elements, an imaging means having imaging elements, a prism arrangement, a light-scattering means and an image reproduction means. A respective imaging element is assigned a number of illumination elements in order to deflect light in the form of a beam onto observers' eyes in a sequential manner in terms of time. | 12-10-2009 |
| 20100067077 | Holographic Reconstruction System with Optical Wave Tracking Means - A holographic projection system has an optical wave tracking system which adjusts the propagation direction of a modulated wavefront. It provides an adjustable wave tracking system which aligns the modulated wave with a desired eye position of one or more observers and follows the movements of the observer. The system comprises spatial light modulation means which modulate a wave with holographic information for the purpose of holographic reconstruction. The optical wave tracking provides the light path of the modulated wave with a desired propagation direction which guides the modulated wave out of the reconstruction system via a light exit position of a display screen. Position control means set adjustable tracking mirror means in terms of their inclination to a reflection direction for reflecting the modulated wave and deflection means, which are located in the set reflection direction, reflect the wave via the display screen into the desired propagation direction. | 03-18-2010 |
| 20100165430 | Holographic Reconstruction System and Method with an Enlarged Visibility Region - A holographic reconstruction system and a corresponding holographic reconstruction method are disclosed. The holographic reconstruction system comprises light source means for providing substantially coherent light, reconstruction means for holographically reconstructing a scene and for producing a visibility region from where the viewer can view the holographically reconstructed scene, and deflection means for positioning the visibility region. The aim of the invention is to improve the visibility region of a holographic reconstruction system. To achieve this aim, the holographic reconstruction system comprises deflection drive means for continuously rotating or pivoting the deflection means about a rotational axis at a rotary frequency, thereby displacing the visibility region. The invention allows one or more viewers to view the scene reconstructed by means of the holographic reconstruction system from different positions while facilitating the implementation of the holographic reconstruction system with conventional means. | 07-01-2010 |
| 20100284049 | Holographic Reconstruction System and Method with a Sequence of Visibility Regions - A holographic reconstruction system and method for the three-dimensional reconstruction of object light points of a scene is disclosed. The system includes spatial light modulation means which modulate light waves capable of interference with at least one video hologram, focusing means which focus the modulated light waves so that a viewer can view the reconstructed object light points of the scene from a visibility region that is thereby produced by focusing, and deflection means which position the visibility region by aligning the modulated light waves. The holographic reconstruction system includes deflection control means for controlling the deflection means to sequentially adjust the visibility region to different contiguous viewing positions, and light controlling means for switching the light waves in synchronicity with the deflection control means. | 11-11-2010 |
