HOLOGRAPHIC STORAGE SYSTEM WITH IMPROVED DATA PAGE QUALITY, WITH A SPECIAL OPTICAL FILTER OR A SPECIAL LIGHT SOURCE

摘要

PURPOSE: A holographic storage system with improved data page quality is provided to restore sharper images of data pages to make a lower bit error rate, thereby compensating low-band filtering of holograms.;CONSTITUTION: High frequency components of a reference beam(2) and a target beam(1) are emphasized by an optical filter(7) arranged on a Fourier plane. A light source(9) adaptive for generating the reference beam and the target beam is arranged on the Fourier plane. A light beam emitted by the light source includes stronger strength from the center to the edge.;COPYRIGHT KIPO 2010
