Methods and devices are described for creating and printing holographic stereograms and holographic optical elements using computer rendered images or using computer processed images. Various embodiments of the system may utilize interchangeable band-limited diffusers and reference-beam masking plates.

Method and apparatus for recording holographic stereograms elements using replacable elements

Methods and devices for creating and printing variable size and variable resolution holographic stereograms and holographic optical elements can generate one-step, full-color, full-parallax holographic stereograms using a reference beam-steering system that allows a reference beam to expose a holographic recording material from different angles. One method includes selecting, for each of a plurality of viewing zones, a respective scene; generating a computer model of each scene; and determining, for each of a plurality of elemental holograms for a holographic stereogram, viewing zone mask volumes. For each elemental hologram and for each viewing zone mask volume, an image is rendered of the selected scene enclosed by the viewing zone mask volume. The rendering is based at least in part on the computer model of the selected scene. After the rendering is complete for each of the viewing zone mask volumes, a composite rendered image is generated for the elemental holograms.

Method and apparatus for recording one-step, full-color, full-parallax, holographic stereograms

Holographic stereograms and holographic optical elements are printed using computer rendered images of three-dimensional computer models or using computer processed images. A coherent beam is split into object and reference beams that interfere with each other at an elemental hologram on a holographic recording material. A voxel-control lens placed in the path of the object beam and in close proximity to the holographic recording material can be used to control the resolution of a holographic stereogram. Interchangable band-limited diffusers and reference-beam masking plates can assist exposure of the elemental hologram and avoid exposing portions of the holographic recording material that are not part of the elemental hologram.

A distributed system for producing holographic stereograms (holograms). A data acquisition station is typically remote from image processing, printing, and replicating stations. The data acquisition station is designed to maximize customer convenience, and may be the customer's own personal computer. The data acquisition station is further designed to accept a wide variety of source data and to perform whatever processing is required to deliver image data to the image processing station in an acceptable format. The data acquisition station further has processing capability to display preview images, which may be assembled by programming executing at the data acquisition station or downloaded from a server.
