Abstract: An apparatus is disclosed for producing an optical display comprising an optical waveguide including a first diffractive part arranged to receive display light and to diffract the display light into an angle for guided propagation along the optical waveguide. A second diffractive part of the waveguide is optically coupled to the first diffractive part by the optical waveguide and is arranged to receive and to diffract light from the first diffractive part to an angle for output from the optical waveguide. Those external surfaces of the waveguide against which guided light reflects internally are coated with a meta-material having a refractive index of value less than 1.0 (one).

Abstract: A binocular display device comprising two ocular assemblies (1A, 1B) to be worn by a user concurrently with one respective ocular assembly at each eye. Each ocular assembly comprises an outer optical part having a positive optical strength (2A, 2B), an inner optical part (4A, 4B) having a negative optical strength and a transparent slab waveguide display part (3A, 3B) in between them. Substantially collimated display light is output from the waveguide for display, and external light of an external scene is transmitted through the waveguide from the outer optical part for viewing concurrently with the display light. The inner optical part imposes a divergence on the received display light to generate a virtual focal point (f) substantially common to each ocular assembly. In use, an image conveyed by the display light is superimposed on the external scene as a three-dimensional (3D) image when viewed through the binocular display device.

Abstract: A waveguide structure for a head up display in which a reflective output coupling structure is formed of a separate, but connected, component to a main waveguide. Light is coupled from the main waveguide to the output coupling structure by evanescent wave coupling. In a method of manufacture for such a waveguide the output coupling structure is attached to the main waveguide using an optical feedback technique.

Abstract: A waveguide structure for a head up display in which a reflective output coupling structure is formed of a separate, but connected, component to a main waveguide. In a method of manufacture for such a waveguide the output coupling structure may be formed by depositing a material on a main waveguide, impressing the reflective structure into that material, and curing the material.

Abstract: An optical component for a display apparatus comprises an optical waveguide part (11) arranged to guide light therealong between surface parts thereof by internal reflection, an input part (13) arranged to receive light and direct the received light into the optical waveguide part, and an output part comprising a partially transmissive angularly reflective optical coating (25) arranged upon a surface part of the optical waveguide part. The output part is optically coupled to the input part by the optical waveguide part to receive guided light and to transmit some but not all of said guided light out from the optical waveguide part. The angularly reflective optical coating extends along a dimension of the optical waveguide part to expand the guided light in said dimension along the output part by repeated partial transmission thereof for output.
