Holographic storage system with improved beam overlap |
摘要 |
An apparatus and a method for reading from and/or writing to holographic storage media using a coaxial arrangement of an object beam and one or more reference beams or a coaxial arrangement of a reconstructed object beam and one or more reference beams is proposed. A focus of the one or more reference beams within a holographic storage medium is shifted along the optical axis relative to a focus of the object beam or the reconstructed object beam.
