Abstract
An apparatus and method are disclosed for replicating a hologram. The apparatus comprises an assembly operable to position a hologram in proximity to holographic recording material. The apparatus further comprises a beam steering unit operable to direct a beam at component portions of the hologram to replicate the component portions onto a holographic recording material. The beam steering unit is further operable to enable independently variable angles of incidence at which the beam strikes each component portion.
