Holographic storage system with improved data page quality

摘要

The present invention relates to a holographic storage system having an improved data page quality. The holographic storage system includes a special optical filter (7) or a special light source (9). According to the invention, the high frequency components of a reference beam (2) and/or an object beam (1) are emphasized. This is achieved by an optical filter (7) arranged in a Fourier plane, which has a higher attenuation at the center than at the edge. Alternatively, an adapted light source (9) for generating the reference beam (2) and/or the object beam (1) is arranged in a Fourier plane. The light beam emitted by the light source (9) has a higher intensity close to the edge than at the center.
