20080241706 | HOLOGRAPHIC DATA STORAGE MEDIUM AND FABRICATION METHOD THEREOF - A holographic data storage medium and a fabrication method thereof are provided. First, a precursor solution including an ultraviolet curable adhesive composition including a monomer having at least one (meth)acryloyl group in the molecule and an oligomer having at least two (meth)acryloyl groups in the molecule, a photopolymerizable organic compound and a photoinitiator including 2, 4, 6 trimethyl benzoldiphenyl phosphine oxide is provided. Next, a first substrate and a second substrate are attached to one another such that a gap is formed between the first and second glass substrates. Next, the precursor solution is filled into the gap. Next, the precursor solution between the first and second substrates is irradiated with a light in an atmosphere of an inert gas to induce photo-polymerization reaction to form the recording layer. | 10-02-2008 |
20080252953 | Holographic Storage And Regeneration System Having Servo Mechanism - A holographic storage and regeneration system includes a holographic recording medium, a light source, a spatial light modulator, and a conjugate servo light guidance portion. The light source generates a signal light and a reference light. The spatial light modulator modulates the incident signal light and makes it incident onto the medium along the incident direction of the signal light. The guidance portion guides a reference light to incident onto the medium in one direction and reflects it in another direction. A reference light and a signal light interfere with each other to produce a holographic interference fringe. The reflected reference light is guided into a first image sensor to be used to analyze the incident angle of the reference light. When the reference light incidents onto the fringe of the medium through the guidance portion in a reverse direction relative to another direction, a conjugate regenerated light is generated. | 10-16-2008 |
20090040577 | System and method for holographic storage - A system and a method for holographic storage mainly involve forming a holographic interference pattern in a holographic recording medium. The holographic storage system utilizes a light source to emit a coherent beam. The coherent beam is irradiated to a first reflector to form a divergent beam. The divergent beam is then irradiated to a second reflector to form collimating beams (a signal beam and a reference beam). The signal beam goes through a spatial light modulator (SLM) and is modulated by the SLM. After that, the reference beam and the modulated signal beam are irradiated to a convergent unit, and are directed to the holographic recording medium for forming the holographic interference pattern. The holographic storage system that the light source is split into a signal beam and a reference beam by a set of reflectors according to the reflection principle without involving refraction may employ wavelength multiplexing. | 02-12-2009 |
