The Du Pont OmniDexTM Replicator uses a unique cylindrical scanning geometry for continuous production of holographic images. The replicator is designed to contact copy reflection holograms into the OmniDexTM family of holographic imaging films. The continuously moving web is coupled to a master hologram which is mounted on a cylinder and scanned to record the copy. The typical production rate is 5 square feet per minute. Examples presented and discussed.
