  • Patent number: 11029521
    Abstract: A head-mounted device may have a transparent display. The transparent display may be formed from a display unit that provides images to a user through an optical coupler. A user may view real-world objects through the optical coupler while control circuitry directs the transparent display to display computer-generated content over selected portions of the real-world objects. The head-mounted display may also include an adjustable opacity system. The adjustable opacity system may include an adjustable opacity layer such as a photochromic layer that overlaps the optical coupler and a light source that selectively exposes the adjustable opacity layer to ultraviolet light to control the opacity of the adjustable opacity layer. The adjustable opacity layer may block or dim light from the real-world objects to allow improved contrast when displaying computer-generated content over the real-world objects.

  • Patent number: 10082668
    Abstract: A headset for virtual reality applications includes an optical element configured to modify light from an electronic display in the headset and to direct the modified light to a user. The optical element may include a Fresnel lens secured to a lens by securing the Fresnel lens to a mold and inserting a casting material into the mold so the casting material forms the lens and a portion of the casting material exists on and past an edge of the Fresnel lens. This encases the edge of the Fresnel lens in the casting material, securing the Fresnel lens to the lens.

  • Patent number: 10046705
    Abstract: Provided is a blind spot assist device capable of more easily showing the image of a blind-spot zone continuously with the image directly viewed by a viewer. The blind spot assist device shows the image of the blind-spot zone blocked by an obstacle, and is provided with a pair of parallel plane mirrors to which light representing the image is incident, the pair of parallel plane mirrors comprising a semitransparent plane mirror and a plane mirror opposed to each other. The semitransparent plane mirror is provided on the viewer side for reflecting part of the light and transmitting part of the light. The plane mirror reflects the light to the semitransparent plane mirror. The pair of plane parallel mirrors is provided in such a manner that the width in a direction perpendicular to the travel direction of the light decreases gradually toward the travel direction of the light.

  • Patent number: 9979936
    Abstract: In a projection system, a nonaxisymmetric aspheric surface is used as a surface that is located in a position where in a pencil of light of video image light that exits from each of two points in different corner regions in an image plane that is a light exiting plane of an image display apparatus, light components that should reach a viewer's eyes do not intersect one another, whereby the size of an optical system can be further reduced and the size of an overall apparatus can therefore be reduced with a variety of types of optical precision, such as the resolution and angle of view, maintained.

  • Patent number: 9835774
    Abstract: Each of a plurality of optical elements that are arrayed in a lattice pattern in a screen member which diffuses a laser beam incident from a projector to guide the laser beam toward a projection surface has a curved surface on a side thereof, and the curved surface has a common convexly curved shape, and diffuses the laser beam which is emitted from the curved surface toward the projection surface. The respective optical elements include a plurality of reference elements which serve as a reference and a plurality of peripheral elements which are adjacent to the respective reference elements. The respective reference elements and the respective adjacent peripheral elements are formed by offsetting surface vertexes of the curved surfaces in a stepwise manner. Offset amounts generated between the respective reference elements and the respective adjacent peripheral elements are different from each other.

  • Patent number: 9720239
    Abstract: A half mirror layer has an angle dependency in which when an angle of incidence becomes larger than the angle of incidence range of image light, reflectance increases, such that it is possible to prevent unintended light, which is emitted to a light transmitting member from a light guiding member and is reflected inside a light transmitting member, from being returned to a light emission portion of the light guiding member after passing through the half mirror layer as a reflective film at a relatively large angle of incidence. Therefore, it is possible to prevent the image light passed through the light transmitting member from becoming ghost light while mitigating the demand for increasing processing accuracy of the light transmitting member, and bonding accuracy between the light guiding member and the light transmitting member, to provide a high quality virtual image displayed by a virtual image display device.
