Abstract: 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.

Abstract: An apparatus is disclosed that includes a transparent support structure having an upper surface and a lower surface. The lower surface is configured to be supported by one or more outer walls of a display module. The upper surface is configured to support imaging optics associated with the display module. The upper surface coincides with an imaging plane associated with the display module. The thickness of the transparent support structure is selected to permit light entering the lower surface proximate to the one or more outer walls to pass through to the upper surface and reach the outer edge of the one or more outer walls without being substantially blocked.

Abstract: 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.

Abstract: Hologram production devices can include holographic recording material deposition systems to deposit holographic recording material as needed by the hologram production device. Various nozzles, ink jets, and similar devices can be used to deposit one or more components of the holographic recording material on to an appropriate substrate. If needed, the material is pre-processed to, for example, provide material stability for the holographic recording material. Once holograms are recorded in the holographic recording material, the material can be post-processed as desired.

Abstract: Hologram production techniques can combine source data representing realistic information describing an environment with source data providing representational information describing a feature of the environment and/or some object interacting with the environment. The combined data is used to produce holograms, and particularly holographic stereograms including features that enhance the visualization of the environment depicted in hologram. A haptic interface can be used in conjunction with such holograms to further aid use of the hologram, and to provide an interface to secondary information provided by a computer and related to the images depicted in the hologram.

Abstract: Characterization of hologram elements (hogels) produced using specially designed test pattern images provides more accurate information that can be used to render images for use in hogel production. Once a test pattern is selected, one or more hogels are recorded in a holographic recording material using a spatial light modulator displaying the test pattern image. Recorded hogels can then be played back to produce an image of the test pattern. Characterization of this image yields information that is used to select angles used to render oblique parallel projections of a computer graphics scene. The rendered projections are then used to record hogels that will produce images with reduced distortion.
