Abstract
An image display system, e.g. for projection type displays, has an electrically addressed spatial light modulator or EASLM (1) and an optically addressed spatial light modulator or OASLM (5). An image formed on the EASLM (1) is transferred to a part of the OASLM (5) by an image transfer means (3) and the image produced by the OASLM (5) is formed from a plurality of successive images formed by the EASLM.
Claims16
An image generating device comprising;
- an electrically addressable spatial light modulator for forming a plurality of successive images;
- an optically addressable spatial light modulator for producing an image;
- and
- an image transfer apparatus for relaying the images from the electrically addressable spatial light modulator to the optically addressable spatial light modulator,
- wherein the image produced by the optically addressable spatial light modulator is formed from the plurality of successive images formed by the electrically addressable spatial light modulator.

An optical switch comprising:
- an electrically addressable spatial light modulator for forming a plurality of successive images;
- an optically addressable spatial slight modulator for producing a computer generated hologram from said plurality of successive images;
- image transfer means for relaying the plurality of successive images from the electrically addressable spatial light modulator to the optically addressable spatial light modulator, and
- an optical waveguide, responsive to said optically addressable spatial light modulator, for transmitting the computer generated hologram.

An image generating device comprising:
- an electrically addressable spatial light modulator for forming a plurality of successive images;
- an optically addressable spatial slight modulator for producing an image from said plurality of successive images;
- image transfer apparatus for relaying the plurality of successive images from the electrically addressable spatial light modulator to the optically addressable spatial light modulator;
- and
- a projector for projecting the image from the optically addressable spatial light modulator onto a surface, from which the image from the optically addressable spatial light modulator is viewed.
