VOLUME HOLOGRAM REPLICATOR FOR TRANSMISSION TYPE GRATINGS

摘要

A holographic replicator configured to mass-manufacture volumetric transmission holograms and including an imaging tank having a holographic master plate opposing a pneumatic absorber. When a segment of a recording film, moveable with respect to the master plate, is placed between the master plate and the pneumatic absorber, the pneumatic absorber is repositioned in space to locks the segment of the recording film between the master plate and the pneumatic absorber.
