Abstract:
An optical device includes a range of angularly selective reflectors are contained within an optical waveguide substrate and substantially optimized according to their reflector order within the sequence of reflectors. This configuration of reflectors ensures that the required angular information is passed through to the correct reflector within the sequence. The angular response in addition reduces or eliminates formation of secondary images carried to successive reflectors, resulting in undesired artefacts.

Claim (Index 21):
A computer-implemented method of determining optical profiles of reflectors for an optical device, the method comprising in a computer simulation:\n designating optical properties of an optical waveguide substrate defining a plurality of reflectors spatially distributed in a sequence along the optical waveguide substrate; for each reflector, designating surface properties and associating the surface properties with the reflector within the waveguide substrate; simulating a light ray source at an eye-box plane; reverse tracing light rays from the light ray source into said optical waveguide, wherein the step of reverse tracing light rays comprises reverse tracing said light rays from different positions across the eye-box plane into said optical waveguide; based on the defined reflector surface properties and the waveguide geometry, determining the angles of incidence of the light rays from the different positions across the eye-box plane from the eye-box light source that are directly and indirectly incident on the reflectors; and according to the determined angles of incidence of the rays directly and indirectly incident on the reflectors from different positions across the eye-box plane, determining the optimized or required selective notch filter angular response of each reflector to provide the optical device with a net optical intensity response over a range of angles of incidence with respect to the reflectors that is substantially uniform at different positions across the eye-box plane.
