APPARATUS AND METHOD FOR STORAGE AND READ-OUT OF HOLOGRAPHIC INFORMATION

PROBLEM TO BE SOLVED: To provide an apparatus for increasing speed and reliability of storage of holographic information, and a method for using the apparatus. SOLUTION: The holographic information recording apparatus 200 is provided with a laser light source 105, a beam splitter 110, and a reflective spacial light modulator 210. The beam splitter 110 provides a reference beam 220 and a data carrier beam 230, the reference beam 220 is directed without reflection toward a holographic data storage medium 195. The data carrier beam 230 is reflected off the reflective spatial light modulator 210 to form data beam 240 comprising an image of information. The reference beam interacts with the data beam 240 to form a hologram 250 comprising the image. That hologram 250 is encoded in a holographic data storage medium 195. COPYRIGHT: (C)2008,JPO&INPIT
