|20120236219||PHASE MODULATOR FOR MODULATING LIGHT INTERACTING WITH THE PHASE MODULATOR - A phase modulator for the modulation of the phase of circular polarised light which interacts with the phase modulator. The phase modulator has a first and a second substrate, an electrode arrangement and a liquid crystal layer with liquid crystal molecules. The first substrate is disposed adjacent to the second substrate. The liquid crystal layer is disposed between the two substrates. The first substrate has a first surface, and the second substrate has a second surface. The liquid crystal molecules situated next to the first surface are oriented substantially parallel to the first surface. The liquid crystal molecules situated next to the second surface are oriented substantially perpendicular to the second surface. An in-plane component of the liquid crystal molecule orientation can be set within an angular range of about 180°, e.g. between 99° and +90° related to a specifiable central orientation.||09-20-2012|

|20100097671||Head-Mounted Display Device for Generating Reconstructions of Three-Dimensional Representations - A head-mounted display device for generating reconstructions of three-dimensional representations comprising a frame, in which at least one light source, at least one optical system and at least one encodable light modulator are situated, wherein the light modulator with an encoding of a wavefront of the three-dimensional representation in the encoding area is positioned at the place of an observer window defined in an observer plane or the light modulator with an encoding of a hologram of the wavefront of the three-dimensional representation in the encoding area is positioned in the region closely in front of the observer window for transforming the hologram into the observer window. When the light modulators are illuminated, complex wavefronts of the three-dimensional representation are situated in the observer window and the reconstruction of the three-dimensional representation is visible in a visual cone spanned by the observer window and the light modulator.||04-22-2010|
|20100097439||MOBILE TELEPHONY SYSTEM COMPRISING HOLOGRAPHIC DISPLAY - 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.||04-22-2010|
|20100033780||Method for Generating Computer-Generated Video Holograms in Real Time by Means of Propagation - The invention relates to a method for generating video holograms in real time for a holographic reproduction device using at least one light modulator means in which a scene split into object points is encoded as a whole hologram in the form of the reconstruction of a visibility region in a periodicity interval of the reconstruction of the video hologram. The reconstruction of an individual object point (OP) only requires part of the whole hologram encoded on the light modulator means. The invention is characterised in that, for each object point, the contributions for propagation of the light waves in the visibility region can be determined from at least one look-up table.||02-11-2010|
