摘要： The present invention relates to a holographic storage system having an improved data page quality. The invention further relates to an optical filter (7) and to a light source (9) suitable for use in such a holographic storage system.
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.
