摘要： A large-area collimated beam (1) of radiation is formed by re-directing a beam of small projected area off one or two orthogonal surfaces (11, 12) which are faceted or have a non-specular reflection angle and which spatially distribute the incoming (1) beam across their surface area. Preferably there are two expansion stages, one for each dimension. If the input beam (1) is linearly polarised then the output beam will also be polarised. The polarisation will undergo a rotation through 90 degrees. The beam expander is compact and suitable for use in liquid-crystal flat-panel displays.

摘要： A flat-panel projection display comprises a slab waveguide having a preferably embossed diffraction grating on one face, a lens for directing light into an edge of the waveguide, and in the focal plane of the lens a liquid-crystal modulator for modulating the intensity of the light as a function of lateral position and elevational direction of travel. The light is ejected from the slab waveguide by the grating at angles corresponding to the input angles, giving a virtual display. The light from the modulator can be expanded in one dimension by passing through a magnifying waveguide, followed by scattering in the plane by a screen and projection by a lens at the other end of the waveguide. Head-up and 3-D displays can be constructed using this principle.

摘要： A display video apparatus which provides a three dimensional image broadly comprises a backlighting apparatus for projecting beams of light in selected directions, a spatial light modulator for displaying images back-lit by the back-lighting apparatus, and a control system coupled to both the spatial light modulator and the backlighting apparatus. The control system causes a plurality of images of an object to be formed in succession on the spatial light modulator with each image being a view of the subject from a different angle, and each image being viewable only from particular angles. The images are formed one at a time on the spatial light modulator with a plurality of images constituting a single frame of a video picture. The backlighting apparatus preferably includes a two dimensional display device for emitting spots of light at selected locations along the two dimensional display, and a lens system for refracting light emitted by the two dimensional display device. The lens system can comprise a single lens or an array of lenses located between the two dimensional display and the spatial light modulator. The lens or lens array refracts beams emanating from a spot of light on the two dimensional display into substantially parallel rays.

摘要： A flat-panel projection display comprises a transparent slab and integral area grating, a transparent rod with rectangular cross-section and integral linear grating, arranged along the edge of the slab, and a small video projector. The projector is arranged to direct a virtual image into the end of the rod, directly or via mirrors, the light travelling along the rod via total internal reflection. The linear grating diverts the light into the plane of the slab, and the area grating projects it out of the slab towards a viewer, so that the viewer sees an image at infinity.

摘要： A light guide with input and output faces (2, 3a) is polar- symmetric about the first face (2) and has optical properties such that the angle at which a ray is injected into the first face determines the position at which it leaves the second face (3a) . The light guide includes a tapered transparent sheet (3) , light from the first -.face entering at the thick end of this sheet, and the second face forming one face of the tapered sheet. An input /output slab (4) adjoins the tapered sheet (3) for fan-out of light from the first face (2) to the tapered sheet, and a transition region (8) is located between flat and tapered sheets. Preferably the light guide further includes a prism device (20) for folding the light so that the flat and tapered sheets can be folded over each other. A method of making such a prism is also disclosed.

摘要： A tapered-waveguide display apparatus includes an input waveguide (2) in the form of a slab, into one end of which light can be injected from a projector (6) so that it bounces along the waveguide and exits at the other end, and a tapered output waveguide (1) adapted to receive light from the input waveguide at its blunt end, that then bounces at ever steeper angles until it reaches the critical angle, at which point it is emitted from the face of the taper. In order to eliminate dark gaps in the display the tapered waveguide's thickness profile is varied so that light bounces the same number of times in total before leaving the tapered waveguide.
