Abstract:
The present invention concerns methods and devices for creating and printing variable size and variable resolution holographic stereograms and holographic optical elements using computer rendered images of three-dimensional computer models or using computer processed images. The present invention is an apparatus and method for printing one-step, full-color, full-parallax holographic stereograms utilizing a reference beam-steering system (400) that allows a reference beam (25) to expose a holographic recording material (70) from different angles. The present invention may also utilize a voxel-control lens (500) placed in the path of the object beam (20) and in close proximity to the holographic recording material (70) to control the resolution of a holographic stereogram. The present invention may also utilize interchangeable band-limited diffusers (45) and reference-beam masking plates (65). The present invention incorporates viewing zone techniques to the rendering process for one-step, holographic stereograms to produce animated, one-step holographic stereograms.
Abstract:
An apparatus and method are disclosed for replicating a hologram. The apparatus (850) comprises an assembly operable to position a hologram (860) in proximity to holographic recording material (862). The apparatus further comprises a beam steering unit (856) 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.
