  • Holographic storage system with reduced noise
    Patent number: 8068263
    Abstract: An apparatus for reading from and/or writing to transmission type holographic storage media is proposed, and more specifically a coaxial type apparatus for reading from and/or writing to transmission type holographic storage media with two or more reference beams, which has an improved Signal to Noise Ratio. The apparatus has a coaxial arrangement of two or more reference beams and an object beam or a reconstructed object beam. The reference beams are arranged on a circle around the object beam or the reconstructed object beam in a Fourier plane of the apparatus behind the holographic storage medium. A mirror is located in or close to this Fourier plane, which is designed such that it reflects the object beam or the reconstructed object beam without reflecting the reference beams.
