Abstract
The present invention relates to a system and method for displaying and capturing holographic true 3D images. The system comprises elements which may form both a wide viewing angle holographic true 3D display and a holographic true 3D video camera. The system mainly comprises a light source, a spatial light modulator or an electro-optical capturing device in different embodiments of the invention, a curved mirror, a computer and a beam splitter and opaque mask in some embodiments of the invention.
Claims11
A holographic true 3D apparatus displaying a true 3D image, comprising:
- at least one light source for providing a collimated light beam,
- at least one belt-shaped mirror;
- at least one spatial light modulator;
- at least one curved mirror;
- at least one computer;
- wherein:
- the spatial light modulator covers an aperture of the curved mirror as a lid except for an opening to allow an outgoing image-forming light to exit;
- the light which originates from the light source and is reflected by the belt-shaped mirror illuminates the spatial light modulator;
- fringe patterns representing the eventual 3D image are written on the spatial light modulator;
- the spatial light modulator modulates light incident onto it according to said fringe pattern;
- the light modulated by the spatial light modulator is coupled to the curved mirror and reflects from it to exit from said opening to form a true 3D video image;
- and
- the computer drives the spatial light modulator by transferring and writing the fringe patterns to the spatial light modulator.

A method of displaying a true 3D video image, the method, comprising:
- reflecting a collimated light beam from a light source by a belt-shaped mirror to illuminate at least one spatial light modulator located to cover an aperture of a curved mirror as a lid except for an opening to allow an outgoing image-forming light to exit;
- writing fringe patterns representing the eventual true 3D video image on the spatial light modulator with a computer;
- modulating light incident onto the spatial light modulator according to said fringe pattern;
- and
- coupling the light modulated by the spatial light modulator to the curved mirror and reflecting from it to exit from said opening to form the true 3D video image.
