Abstract
Large format, highly selective display screens can be formed from a plurality of holographic optical elements. In accordance with the teachings of the present invention, systems and methods are described to provide a holographic screen for display of static and/or dynamic projected conventional two-dimensional images, two-dimensional stereograms, and holographic stereograms. One aspect of the present invention includes presenting live-image three-dimensional displays using an array of two-dimensional data projectors. Another aspect includes projecting and enlarging static or dynamic source three-dimensional images (real objects, holograms, or other autostereoscopic images).
Claims24
A system for projecting an image comprising:
- a screen formed from a plurality of holographic optical elements, at least one of the plurality of holographic optical elements being formed from a computer graphics image;
- and
- at least one projector for directing an image onto the screen, the screen presenting at least one viewzone through which an observer can view the image, the at least one viewzone being formed by the at least one of the plurality of holographic optical elements, and presenting a two-dimensional window appearing in space.
A system for producing and observing at least one autostereoscopic image comprising:
- a screen formed from a plurality of holographic optical elements, at least one of the plurality of holographic optical elements being formed from a computer graphics image;
- at least two projectors for directing an autostereoscopic image onto the screen;
- and
- the screen having at least two viewzones through which at least one observer may view the autostereoscopic image, wherein at least one of the at least two viewzones is formed by the at least one of the plurality of holographic optical elements, and presents a two-dimensional window appearing in space.
A system for producing and observing at least one autostereoscopic holographic display comprising:
- a screen formed from a plurality of holographic optical elements, at least one of the plurality of holographic optical elements being formed from a computer graphics image;
- a three-dimensional image source with light coming therefrom and impinging upon the screen;
- the holographic optical elements cooperating with each other to produce the at least one autostereoscopic holographic display using the impinging light;
- and
- the screen having at least two viewzones through which at least one observer may view the autostereoscopic holographic display, wherein at least one of the at least two viewzones is formed by the at least one of the plurality of holographic optical elements, and presents a two-dimensional window appearing in space.
