20100259804Illumination Unit Comprising an Optical Wave Guide and an Imaging Means - Disclosed is an illumination unit comprising a strip-type optical wave guide and an imaging means, and providing a very high light efficiency with a reduced number of primary light sources. The illumination unit enables the production of a coherent plane wave field having a temporal and spatial coherence required for holographic reconstructions. The strip-type optical wave guide contains extraction elements for extracting injected coherent light guided into an observer plane by imaging elements via a controllable light modulation means. During the injection of light, the extraction elements form a grid of secondary light sources which are arranged in the front focal plane of the imaging elements and carry out the spatial coherence in at least one dimension. A secondary light source and an imaging element are associated with each other in order to guide the extracted light through the controllable light modulation means in a collimated manner.10-14-2010

20090122375Holographic information recording and reproducing apparatus for the same - In a holographic information recording and reproducing apparatus, an optical fiber guides a reference beam toward a recording medium for holographic recording, and a precision rotator is turned, so that the reference beam is incident on the recording medium at different angles and interferes with a data-carrying signal beam to complete the recording of holographic information on the recording medium. To reproduce the holographic information, the optical fiber guides a reading beam, and the reading beam is incident on the recording medium at an angle the same as the reference beam for the recording to reproduce the holographic information stored on the recording medium. With the optical fiber and the precision rotator, a simplified light path system and a wide range of incident angles for the reference and reading beams may be achieved, and the transmissive, reflective, and 90-degree holographic storage techniques may be integrated in one single apparatus.05-14-2009
