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 1):
An optical device comprising\n an optical waveguide substrate; and a plurality of reflectors spatially distributed in a reflector sequence along a propagation axis of said optical waveguide substrate; wherein said plurality of reflectors comprises a plurality of angular selective notch filter optical reflectors; wherein each angular selective notch filter optical reflector is configured both to partially reflect and partially transmit light rays having angles of incidence with respect to the reflector which are in a specific transflectance band of angles selected for each particular reflector and to pass or transmit light rays that have angles of incidence above and below the selected specific transflectance band without reflection, or with reduced reflection compared to light rays having angles of incidence within the selected specific transflectance band; wherein the specific transflectance band of each angular selective notch filter optical reflector is selected according to the order of the reflector within the sequence of said reflectors in said optical waveguide substrate; wherein each one of said specific transflectance bands of the plurality of angular selective notch filter optical reflectors is positioned within a range of angles of incidence with respect to the reflectors; and wherein said plurality of angular selective notch filter optical reflectors are further configured to provide the optical device with a net optical intensity response over said range of angles of incidence with respect to the reflectors which is substantially uniform at different positions across an eye-box plane.
