COLLINEAR HOLOGRAPHIC STORAGE DEVICE CAPABLE OF IMPROVING THE STABILITY OF A COLLINEAR HOLOGRAPHY

摘要

PURPOSE: A collinear holographic storage device is provided to remove one part of diffraction beam which is made by reflection lattices.;CONSTITUTION: A writing unit(700) reads data to a collinear holographic storage medium(100). A reading device(800) reads data from the collinear holographic storage medium. A temperature control unit(900) controls the temperature difference of the collinear holographic storage medium in the range of 5~50°C between reading and writing. A lens(400) focuses a reading beam in the collinear holographic storage medium. An image sensor(850) detects a diffraction beam.;COPYRIGHT KIPO 2012
