摘要： A method for processing a sequence of holographic images with a view to playing the images back on a holographic display device to at least one viewer. A subset of wavelet coefficients relevant for the reconstruction of a sub-hologram visible for the at least one viewer from at least one viewing point is selected from a decomposition of at least one holographic image on a wavelet basis and information representative of a location of the at least one viewer in a repository of the display device. In the method, decomposition of the at least one holographic image is carried out on a Shannon wavelet basis.

摘要： For comfortable viewing of a 3-D scene at various viewing angles, a display having a large tracking range for a variable viewer distance is required. A controllable light-influencing element deflects light in coarse steps in a viewer range. Within said steps, the light is deflected by a further controllable light-influencing element continuously or with fine gradation. The light modulation device is suitable in holographic or autostereoscopic displays for guiding the visibility ranges of the image information to be displayed so as to follow the eyes of the viewers.

摘要： This specification relates to an apparatus, system and method of projecting holographic images for a video conference, wherein a user may use the apparatus for telecommunication transmissions. The apparatus also includes biometric verification means for verifying the identity of the user using his/her biometric authentication credentials. Upon verification of the user's biometric sample, a keypad door is opened to reveal a concealed keypad and a camera door is also opened to reveal and release a telescopic camera in the retracted position, enabled for capturing an image (video including picture and audio) of teleconferencing attendees that are within the apparatus' field of view, where the captured image may be transmitted to a receiving holographic video conferencing apparatus, where the captured video image is projected as a hologram, with audio output provided via the speaker/microphone system.

摘要： An analytical method for computing a video hologram for a holographic reproduction device having at least one light modulation means is disclosed, wherein a scene split into object points is encoded as a whole hologram and can be seen as a reconstruction from a visibility region, located within a periodicity interval of the reconstruction. The visibility region, together with each object point of the scene to be reconstructed, defines a sub-hologram and the whole hologram is generated from a superposition of sub-holograms, wherein the complex hologram values of a sub-hologram are determined from the wave front of the respective object point to be reconstructed in a modulator region of the light modulation means, by calculating and evaluating the transmission or modulation functions of an imaging element formed in the modulator region. The object point to be reconstructed is located in the focal point of the imaging element.

摘要： A holographic gun sight has a housing with a viewing end and an opposing target end, a viewing path being defined from the viewing end to the target end. A light source projects a light beam along a path to illuminate a reflection-type holographic optical element (HOE). The HOE reconstructs an object beam with an image of a reticle. The absolute difference between the incidence angle of the light beam on the HOE and the object beam angle is greater than zero and less than or equal to 30 degrees.
