摘要： Examples are disclosed that relate to mixed reality display devices. One example provides a head-mounted display device comprising, a display, a lens system, and a curved Fresnel combiner. The curved Fresnel combiner is configured to direct light received from the display via the lens system toward an eyebox, and is at least partially transmissive to background light.

摘要： An optical combiner includes a two-dimensional (“2D”) array of three-dimensional (“3D”) diffraction element shapes disposed in a first side of a base sandwich layer. Partially reflective elements coat each of the 3D diffraction element shapes. The partially reflective elements collectively form a reflective diffraction grating having magnifying optical power for image light incident on the reflective diffraction grating through an eye-ward side of the optical combiner. A planarization sandwich layer is disposed over the partially reflective elements and has an index of refraction substantially equal to that of the base sandwich layer such that external scene light incident through the external scene side passes through the optical combiner substantially without diffraction while the image light incident through the eye-ward side is reflected and magnified via the reflective diffraction grating.
