    摘要： An optical reflective device for pupil equalization including at least one or more grating structures within a grating medium is disclosed. The grating structures may have reflective axes that need not be constrained to surface normal. The grating structures are configured to reflect light about substantially constant reflective axes across a relatively wide range of wavelengths. The optical reflective device may reflect light towards a specific location, such as an exit pupil or eye box. Each grating structure within the device may be configured to reflect light of a particular wavelength at a plurality of incidence angles.

    摘要： A device including a waveguide having a first waveguide surface and a second waveguide surface parallel to the first waveguide surface is disclosed. The device may include a first volume holographic light coupling element disposed between the first waveguide surface and the second waveguide surface. The first volume holographic light coupling element may be structured to reflect at least a portion of incident light as reflected light. Incident light for which the first volume holographic light coupling element is structured to reflect may have a first angle of incidence within a total internal reflection (TIR) range with respect a first axis corresponding to a surface normal of the waveguide. Incident light for which the first volume holographic light coupling element is structured to reflect may have a second angle of incidence with respect to a second axis different from the first axis.
