A system for recording and reading out holograms in a storage medium including a pattern encoder, a first fourier transform lens with a focal length f , a second fourier transform lens with a focal length f , a detector array, and a first and second prism. The first prism is located between the pattern encoder and the first fourier transform lens, wherein the optical length between the pattern encoder and the first fourier transform lens through the first prism is equal to a back focal length BFL . The second prism located between the second fourier transform lens f and the detector array, wherein the optical path length between the second fourier transform lens and the detector array through the second prism is equal to a back focal length BFL .

System and method for holographic storage with optical folding

The present invention provides a solution to the needs described above through a system and method for holographic storage. The system comprises a laser light source, a first beam splitter for splitting a light beam into an object and reference beam, an elliptical reflector with a first and second focal point, a reflector rotatable about a first axis and a second axis, a pattern encoder, and a holographic storage medium. The reflector is located at the first focal point of the elliptical mirror, and the holographic storage medium is located at the second focal point of the elliptical mirror.

System and method for holographic storage

Holography in which an array of overlapping holograms is recorded or reconstructed in a recording medium, holograms being produced by interference of a reference beam and a signal beam, in which the reference beam is a phase beam which consists essentially of a multitude of rays of varying angle of incidence and non-uniform phase, in which the process comprises changing the orientation of the phase beam for recording or reconstructing different holograms, wherein phase beam orientation is changed relative to the medium while maintaining the medium stationary in order to enable recording or reconstruction of individual holograms at a given location of the medium.
