Abstract: Pre-sensitization techniques can be used in conjunction with holographic recording materials to allow high quality holographic stereograms to be recorded in those holographic recording materials using pulsed lasers. Additional hologram production system hardware and software designs for use with pulsed lasers are disclosed.

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: Certain types of holographic recording materials can be used to updateably record holographic stereograms formed when fringe patterns are generated through interference of an object laser beam containing image information with a reference laser beam. In this manner, calculation of fringe patterns is avoided, and instead perspective information is computed for a scene or object to be displayed, the information is downloaded to display hardware such as a spatial light modulator, and fringe patterns are subsequently generated through interference of an object laser beam containing this information with a reference laser beam in the classic hologram recording scheme. Previously recorded holographic stereograms or component hogels are updated by erasing the stereograms or component hogels and recording updated stereograms or component hogels, or by recording updated stereograms or component hogels in a separate portion of the holographic recording material.

Abstract: Methods for creating a plurality of holographic diffraction grating patterns in a raster scan fashion. In accordance with the method, the desired pattern is made up of a large plurality of individual spots, each spot comprising a holographic diffraction grating of a predetermined grating spacing and angular orientation for that spot. Variation of the angular orientation and/or grating spacing between spots and/or groups of spots provide the desired holographic effect. The spot locations may vary as desired, including locations drawing out a desired pattern, and two-dimensional orthogonal matrices in which a pattern is drawn by variations between spots or group of spots as in a raster scan type image. Various embodiments and methods for creating the same are disclosed.

Abstract: An animated holographic stereogram display and method of creating the same is disclosed. In accordance with the method, a user views a hologram from a fixed relative position, the hologram containing a plurality of stereographic image pairs. A plurality of light sources are appropriately spatially dispersed so that each light source will illuminate the hologram so as to make the one stereographic image pair associated with that light source and viewing position viewable by the user. By using stereographic image pairs which are related to each other and appropriate time sequencing of the light sources, animation of the image pairs may be achieved. Uses of the system include facial animation whereby facial image pairs associated with various phonemes may be sequenced in accordance with a speech signal so that a limited set of image pairs may animate the face for a substantially unlimited vocabulary.

Abstract: Methods and apparatus for providing real time autostereoscopic displays using holographic diffusers are disclosed. In accordance with the method, a diffuse holographic optical element is fabricated whereby an image projected onto the diffused holographic optical element will be viewable only over a limited horizontal extent of less than the separation of a typical viewer's eyes. Then the holographic optical element is used as a projection screen for a plurality of projectors spatially positioned with respect to each other so that the horizontal position within which the image of each projector is viewable is substantially contiguous with the horizontal position of viewability of the respective adjacent projector whereby the autostereoscopic effect is achieved. Various embodiments, including the transmission mode and reflection mode holographic optical elements, are disclosed.
