ABSTRACT:
An apparatus for replicating holographically recorded data, comprising a holographic master media having holographically recorded data thereon; a holographic copy media; a light source for generating a master reference beam and a copy reference beam, coherent with the first object beam, the first master reference beam incident on the holographic master media, the holographic master media diffracting the master reference beam to provide a first object beam; the copy reference beam incident on the holographic copy media; and a first optical relay system, disposed between the holographic master media and the holographic copy media, for relaying the first object beam from the holographic master media to the holographic copy media, the holographic copy media recording an interference pattern between the first object beam and the copy reference beam, thereby replicating at least a portion of holographically recorded data.
