  • Patent number: 11650416
    Abstract: A see-through head mounted display with controllable light blocking includes an optics module comprising a light source and image source positioned on a same side of an angled partially-reflective surface, wherein the light source projects light off the surface to the image source which reflects the light as image light to the surface which transmits the image light along a first axis. The display also includes a flat combiner positioned to reflect the image light off of a first side and simultaneously transmit incident light through the first and a second side, along an optical axis perpendicular to the first axis to provide a view of a displayed image overlaid onto a see-through view of the environment, and a controllable light blocking element arranged generally parallel to the flat combiner and in front of the second side to block light incident on the same optical axis as the image light.

  • Patent number: 11650403
    Abstract: An example device may include a light source, an optical element, and, optionally, an encapsulant layer. A light beam generated by the light source may be received by the optical element and redirected towards an illumination target, such as an eye of a user. The optical element may include a material, for example, with a refractive index of at least approximately 2 at a wavelength of the light beam. The light source may be a semiconductor light source, such as a light-emitting diode or a laser. The optical element may be supported by an emissive surface of the light source. Refraction at an exit surface of the optical element, and/or within a metamaterial layer, may advantageously modify the beam properties, for example, in relation to illuminating a target. In some examples, the light source and optical element may be integrated into a monolithic light source module.

  • Patent number: 11624891
    Abstract: There are provided a lens guide device, a lens moving device, and an imaging apparatus that can accurately position a lens frame regardless of an attitude, such as an imaging direction. A first-rail supports a first-rolling-body so as to allow the first-rolling-body to be rollable in a first-direction parallel to an optical-axis of a first-focus-lens. A second-rail supports a second-rolling-body so as to allow the second-rolling-body to be rollable in the first-direction. A biasing-mechanism supports the first-rolling-body so as to allow the first-rolling-body to be movable in the first-direction, and biases the first-rolling-body toward the first-rail. A third-rail is provided in parallel with the second-rail. The third-rail supports the second-rolling-body so as to allow the second-rolling-body to be movable in the first-direction. Since the first-rail and the second-rail are moved and guided in a first direction by the first-rolling-body and the second-rolling-body, a lens frame is not inclined.
