Abstract: A waveguide device includes a first diffractive element, a second diffractive element, a third diffractive element, and a waveguide element. The first diffractive element is configured to diffract light of a wavelength to propagate with a diffraction angle. The second diffractive element is configured to diffract the light of the wavelength to propagate with the diffraction angle. The third diffractive element is configured to diffract the light of the wavelength to propagate with the diffraction angle. The waveguide element is configured to guide the light of the wavelength to propagate from the first diffractive element to the second diffractive element and the third diffractive element. Diffraction efficiencies of the second diffractive element and the third diffractive element are different.

Abstract: A lens assembly for a head mounted device may be configured to in-couple light from an eyebox region using a number of waveguide systems coupled to a number of image sensors, for example, for one or both lens assemblies in the head mounted device. The waveguide systems may be positioned in the lens assembly. The waveguide systems may be configured to in-couple light from various portions of the eyebox region. The waveguide systems may be configured to couple the light from a center region of the lens assembly to a number of peripheral regions of the lens assembly. The image sensors may be optically coupled to the waveguide systems and may be configured to receive portions of the light from the waveguide systems.
