  • Patent number: 10330887
    Abstract: A head-mounted display in accordance with an embodiment of the present technology includes a display housing and one or more displays within the display housing. The display system further includes a first lens and a second lens, each being operably associated with the one or more displays. A lateral distance between the first and second lenses is adjustable to accommodate users having different interpupillary distances. The display system still further includes a flexible membrane having a region extending between the first and second lenses. The region of the membrane extending between the first and second lenses is configured to resiliently expand as the lateral distance between the first and second lenses increases and to resiliently contract as the lateral distance between the first and second lenses decreases.

  • Patent number: 10295723
    Abstract: A holographic Bragg grating is used as an output element for a waveguide in a lens used for artificial reality. By using a Bragg grating, a number of waveguides can be reduced. The output element has a first super grating and a second super grating written in a single grating layer of the waveguide. The first super grating has a grating vector that is skew to a grating vector of the second super grating to provide both deflection and out coupling for two-dimensional output coupling.

  • Patent number: 9977247
    Abstract: A display can be utilized with an image source. The display includes a collimator and a substrate waveguide. The substrate waveguide sees collimated light from the collimator at an input and provides the collimated light to an output. The collimated light travels from the input to the output within the substrate by total internal reflection. An input diffraction grating is disposed in a first area at the input and an output diffraction grating is disposed in a second area at the output. The second diffraction grating is matched to the first diffraction grating. A combiner alignment detector is not required due to the periscopic effect according to one embodiment.

  • Patent number: 9739990
    Abstract: A mirror structure permitting an undistorted view of the blind spots of a vehicle include a first lens module and a second lens module. The first lens module is mounted on an A-pillar of a vehicle and located outside of the vehicle; the second lens module is opposite the first lens module and mounted inside of the vehicle on the A-pillar. The first lens module focuses light beams which would otherwise be blocked by the A-pillar of the vehicle and transmits the light beams to a front windshield of the vehicle, the light beam passing through the front windshield to reach the second lens module, the second lens module diffusing the light beams into the vision of a driver.

  • Patent number: 7837330
    Abstract: An adapter is provided for adapting an optical instrument, such as a camera (3) or a projector, to capture or display panoramic three-dimensional images. The adapter comprises a plurality of mirrors (1a, 1b, 1c), each of which has a reflective surface which is in the shape of a curved non-circular conic section rotated about an axis of symmetry (15a, 15b, 15c). The reflective surfaces have first foci which are spaced perpendicularly from a longitudinal axis of the adapter and which are angularly spaced around the longitudinal axis. For example, the conic section may be a hyperbola with first foci equidistantly spaced from the longitudinal axis and equiangularly spaced around 15b the longitudinal axis. The axes of symmetry (15a, 15b, 15c) of the mirrors (1a, 1b, 1c) converge to intersect the longitudinal axis at a point which is coincident with the front principal point of, for example, a camera lens (12).

  • Patent number: 6754004
    Abstract: An optical sight for a combat vehicle, intended to be mounted in a weapon turret of the vehicle in order to make possible sight lines at elevations between roughly −10° and 90° of a weapon barrel mounted pivotably about a horizontal axis in the weapon turret. The sight comprises a lower standard sight unit, which deflects vertical incident light by 90° to an eyepiece, and a top mirror, located above the standard sight unit and pivotable in synchronism with elevating movements of the barrel, likewise about a horizontal axis. Positioned above the standard sight unit is a deflection prism which has an upper surface which faces the top mirror, is inclined at roughly 45° to the vertical and is designed to reflect incident light at an angle of roughly 45° to the surface and less, but to transmit light which is incident at roughly 90° to the surface.

  • Patent number: 6731845
    Abstract: A panoramic view of the world surrounding a stationary mast of a submarine is provided by a plurality of small windows disposed circumferentially around the mast and a corresponding plurality of lenses for imaging the fields of view thereof onto coherent fiber optic image bundles. The fields of view of the lenses overlap to provide a complete panoramic view. The exit ends of the image guides are arranged to form a polygonal opening so that a replica of the panoramic view is provided within the opening. A mirror or prism rotating within the opening scans the view replica and directs the scanned image to a stationary television camera. A derotating prism in the path of the directed scanned image rotates at one-half the angular displacement of the image director to compensate for rotation imparted to the scanned image by the image director.

  • Patent number: 6700689
    Abstract: An adjusting device for adjusting a projecting direction of a view comprises the following components. A reflector is pivotally installed in a body case. The body case is formed with an incident hole, first viewing hole and a second viewing hole. A reflector is located within the body case and is pivotally installed thereto. An adjusting button is located on the upper cover. A rotary flange is installed on the adjusting button. Thereby, the user rotates the adjusting button so that a rotary arm is adhered on the adjusting button. When a user desires to see an outer view; by a driving the rotary arm, the reflector is driven to rotate to a predetermined angle. On the contrary, when the user desires to see outer view from the first viewing hole; the user only needs to restore the adjusting button to the original position.

  • Publication number: 20030133204
    Abstract: A derotation mirror system for a common-optical-path panoramic stabilized periscope. The derotation system has a first surface-reflecting mirror, a second surface-reflecting mirror and a third surface-reflecting mirror. Through subsequent reflection of light from the surface of the first surface-reflecting mirror, the second surface-reflecting mirror, the third surface-reflecting mirror and a rotation of the entire derotation mirror system with respect to the Z-axis, the derotation is achieved. Since this invention only requires three reflections, the derotation system allows the lights with various wavebands (such as visible light, infrared light and laser beam). In addition, the derotation system manages to constrain the propagation of the output image vector and the output image vector along the same Z-axis line.
