Abstract
A system for the production of a dynamic image for use in display applications includes a light source (16) which travels via a liquid crystal modulator (18) placed in the path of the light source (16). The output of the LC modulator (18) passes modulated light a lens ray (22) which itself guides light to an optically addressed spatial light modulator (24). The resulting real image from the optically addressed spatial light modulator (24) may be used in two dimensional and three dimensional displays. The addressing frame-rate of the liquid crystal modulator (18) is substantially greater than the frame-rate of the optically addressed spatial light modulator (24).
Claims35
A system for the production of a pattern in display comprising:
- a light source;
- first spatial light modulator having an associated updating frame-rate in the path of the light source;
- relay optics in the path of the light from the first spatial light modulator for guiding the modulated light therefrom;
- a second spatial light modulator having an associated read-out frame-rate in the path of the guided light from the relay optics and arranged to produce a real pattern therefrom for display, wherein the updating frame-rate of the first spatial light modulator is greater than the read-out frame-rate of the second spatial light modulator.
A method of producing a pattern for use in display comprising:
- providing a light source and modulating this light source using a first spatial light modulator having an associated updating frame-rate;
- the method characterised by
- guiding the modulated light via relay optics, disposed in the path of the modulated light to a second spatial light modulator and producing a real pattern therefrom for display, which second spatial light modulator has an associated read-out frame-rate less than the associated updating frame rate of the first spatial light modulator;
- and providing a real pattern from the second spatial light modulator.
