Appl. No.:

11/483482

Inventors:

Gaylord E. Moss - Marina del Rey CA, US

International Classification:

G03H 1/04

US Classification:

359 35, 359 15

Abstract:

An autostereoscopic imaging system is disclosed that provides for a three dimensional display of an image to multiple observers simultaneously from a single pair of stereoscopic projectors. The system provides for high quality immersive imagery using a holographic diffractive optical element that is made and configured to contain multiple holograms of optical diffusers, each of the holograms having a common reference beam and being made with each diffuser in a different location. A pair of projectors placed astride the reference beam virtual focus projects a stereoscopic image onto the diffractive optical element, such that the plurality of holograms reconstructs multiple stereoscopic images at multiple locations corresponding to the location where the diffusers were previously located during the recording of each respective hologram. Methods of making the diffractive optical element with a plurality of holograms are also disclosed. The holograms may be made on separate plates and laminated together, or may be made by simultaneous, sequential, or repeated partial sequential exposures onto a single holographic plate.

Abstract:

A system is disclosed for recording a diffraction optical element providing a stereographic image to an observer includes a monochromatic light source having a characteristic wavelength providing a single source beam and a recording plate made from a material sensitive substantially to the characteristic wavelength. The system also includes at least first, second and third diffusers each having a characteristic wavelength differing from one another, a first beam split from the single source beam received from the monochromatic light source at the wavelength and at least one mirror reflecting a second split beam as a converging reference beam from the light source. The recording plate is exposed to the diffuse light beam separately passing through the first, second and third diffusers and received from the first beam and is exposed to the converging reference beam to form thereby the diffraction optical element.

US Classification:

359 23, 359464

Abstract:

A display device includes a surface configured to be illuminated by at least two directed light beams, and one or more holographic optical elements. The surface is configured and disposed with respect to the holographic optical element to display an autostereo image that is illuminated by the directed light beams wherein the holographic element diffracts the directed light beams to form separate stereo viewing areas. The surface and the holographic optical element may be configured and oriented with respect to each other to enable the directed light beams to be alternately switched in synchronization with left and right stereo images presented on the surface to yield an autostereo view to one or more observers.

US Classification:

350 366

Abstract:

A method of making edge-faded holograms. A holographic recording medium is masked to provide a medium having photo-sensitive and photo-desensitized pixel areas. The photosensitive areas of the masked recording medium are exposed with a holographic image, producing an edge-faded hologram. Both positive and negative image masks may be employed to implement the invention. In a specific embodiment of the invention, the number and/or density of the photo-desensitized pixel areas are arranged in a pattern with the number of desensitized pixel areas increasing with proximity to the edge of the medium. The method may be performed in a single frame procedure or may be performed as a continuous process utilizing a continuous strip of holographic recording medium.

International Classification:

G03H 108

US Classification:

350 366

Abstract:

A computer generated diffraction grating which exhibits multiple order scattering noise is illuminated by a point source to generate a first wavefront which is intersected with a second wavefront to form a desired interference pattern in a recording medium. The point source is moved relative to the recording medium during exposure in order to reduce multiple order scattering noise.

Abstract:

A head-up holographic display for providing a display on a vehicle windshield of a control panel and indications of the vehicle operator's manual movements and manual selection operations on the control panel. The display includes a number of edge-illuminatable hologram layers providing a background display and touch and activation indications. Signals from the control panel selectively illuminate respective layers and portions thereof in response to operations on the control panel to create a windshield display thereof. In a second embodiment, a head-up virtual image background display is provided by a first hologram and dots indicative of the driver's finger position on the control panel are positioned on the background display by selective illumination of a second hologram.

International Classification:

US Classification:

359 3

Abstract:

A pulsed laser provided a pulsed incident beam which impinges a recording assembly which includes a glass substrate and a recording film adhered thereto. The pulse can be singular or multiple. In either event, the duration of each pulse of light is controlled in such a fashion so that the pulse is long enough to enable it to reflect off of a reflecting element to thereby produce a primary reflected beam. In the recording film, the primary reflected beam can interfere with the incident beam to produce the interference pattern in the film. However, the pulse is not of such a duration to allow a noise reflected beam, such as one from a glass-air interface, to pass through the recording film and interfere with the incident beam or primary reflected beam while those beams are still present. Thereby, noise holograms which might otherwise be recorded in the film are precluded while allowing the primary hologram to be recorded.
