摘要： Methods and an apparatus for color holographic display are provided. The method for color holographic display includes modifying a plurality of color component light beams by passing light from each of a plurality of color component light sources through a corresponding one of a plurality of color sub-hologram masks to generate a corresponding plurality of modified color component light beams. The plurality of modified color component light beams are color multiplexed to generate a multiplexed masked color light beam. The multiplexed masked color light beam is shined onto modulated computer generated holographic information corresponding to the object in order to reconstruct the object by diffracting each portion of the multiplexed masked color light beam to a location and at an intensity determined in response to a corresponding portion of the computer generated holographic information to create the object as a color holographic display.

摘要： The present invention discloses a recording medium comprising an improved doped Stoichiometric Lithium Niobate (SLN) crystal for high-speed holographic data storage. The improved doped SLN has an extremely high optical damage resistance of more than 145 kW/cm2 for power density of an incident laser beam along the c axis. The Recording time using the present improved doped SLN is advantageously very short and is about 1 second for a single hologram with a saturated diffraction efficiency of 28.7% at a recording laser beam density of 70 W/cm2. Reliable retrieval of a signal-image written at as low as 1 milliseconds has been performed in the Z-cut doped SLN. The present recording medium is an improved doped SLN of a Z-cut SLN crystal doped with Iron (Fe) and Terbium (Tb). The Terbium (Tb) content within the fluxed melts for growing the improved doped SLN ranges from 10 ppm to 140 ppm.
