摘要： A head mounted display for virtual reality imaging includes a pixel array including multiple pixels configured in a two-dimensional surface, each pixel providing multiple light beams forming an image provided to a user. The head mounted display also includes a first optical element to provide a central portion of a field of view for the image through an eyebox that limits a volume including a pupil of the user, and a second optical element to provide a peripheral portion of the field of view for the image through the eyebox. The second optical element includes a lenslet array to provide a segmented view of the peripheral portion of the field of view that includes at least one of a free form lenslet, a liquid crystal lenslet, a Fresnel lenslet, or a pancake lenslet. A system and a method for using the above head mounted display are also provided.

摘要： A folded-path optical component usable as an ocular lens in a near-eye display is disclosed. The folded-path optical component includes a cavity formed by a pair of spaced apart coaxial curved reflective polarizers, and a partial reflector in the cavity for splitting an impinging light beam to propagate along two optical paths ending at an exit pupil of the optical component. Each optical path includes a reflection from one of the reflective polarizers and a transmission through the other one of the reflective polarizers.

摘要： A head-mounted display (HMD) for improved field of view (FOV) is provided. The head-mounted display (HMD) may include a display element to provide display light. The head-mounted display (HMD) may also include a lens element to provide display light to a user of the head-mounted display (HMD). The head-mounted display (HMD) may further include an optical element comprising at least one waveguide to provide improved central or peripheral field of view (FOV) for the user of head-mounted display (HMD). In some examples, the waveguide may be part of central optics and/or peripheral optics. The waveguide may have a planar waveguide profile or a curved waveguide profile. In some examples, the waveguide may be stacked or may include a graded index (GRIN) layer.

摘要： A device for providing a reverse pass-through view of a user of a headset display to an onlooker includes an eyepiece comprising an optical surface configured to provide an image to a user on a first side of the optical surface. The device also includes a first camera configured to collect an image of a portion of a face of the user reflected from the optical surface in a first field of view, a display adjacent to the optical surface and configured to project forward an image of the face of the user, and a screen configured to receive light from the display and provide the image of the face of the user to an onlooker.

摘要： A system includes a light outputting device configured to output a divergent light. The system also includes a lens configured to convert the divergent light incident thereon from a first side of the lens to a collimated light substantially covering a light receiving region located at a second side of the lens, the lens including a plurality of Fresnel structures formed on at least one of a first lens surface or a second lens surface of the lens. Each Fresnel structure includes a slope facet and a draft facet. At least one of the draft facets is a first type of draft facet configured to not interact with a ray of the divergent light that is non-parallel with the at least one of the draft facets.

摘要： A device includes an array of light emitters configured to generate multiple light beams to form an image, the image having a field of view and a planar waveguide having an edge configured to receive multiple light beams from the array of light emitters, each light beam associated with a portion of the field of view. The device also includes a lens array comprising multiple lenses linearly extended to overlap an edge portion of the planar waveguide, the lenses optically coupling the light beams into the planar waveguide, and one or more output couplers in the planar waveguide configured to direct the light beams into an eyebox, wherein the eyebox forms an area that includes a pupil of a viewer of the image.
