Patent number: 10746989Abstract: A head up display can use a catadioptric collimating system. The head up display includes an image source. The head up display also includes a collimating mirror, and a polarizing beam splitter. The light from the image source enters the beam splitter and is reflected toward the collimating mirror. The light striking the collimating mirror is reflected through the beam splitter toward a combiner. A field lens can include a diffractive surface. A corrector lens can be disposed after the beam splitter.Type: GrantFiled: September 10, 2018Date of Patent: August 18, 2020Assignee: Rockwell Collins, Inc.Inventors: Robert D. Brown, Eric P. Stratton

Patent number: 10746991Abstract: A waveguide structure for a head up display in which a reflective output coupling structure is formed of a separate, but connected, component to a main waveguide. In a method of manufacture for such a waveguide the output coupling structure may be formed by depositing a material on a main waveguide, impressing the reflective structure into that material, and curing the material.Type: GrantFiled: April 10, 2017Date of Patent: August 18, 2020Assignee: BAE SYSTEMS plcInventors: James Raymond Leighton, Rory Thomas Alexander Mills, Michael David Simmonds

Patent number: 10746992Abstract: A HUD including a projection display unit, a housing, a cover, a region detecting unit, and a display control unit is provided. The projection display unit includes a light modulating unit spatially modulating light emitted from a light source based on input image information and projects modulated image light onto a windshield of an automobile to display an image. The housing accommodates the projection display unit and has an opening portion through which the modulated image light exits. The cover covers the opening portion. The region detecting unit detects an object adhesion region in which an object is adhered to the cover. The display control unit controls the image information to be input to the light modulating unit to control the image to be displayed by the projection display unit. The display control unit causes the projection display unit to display an outline of the object adhesion region.Type: GrantFiled: May 21, 2019Date of Patent: August 18, 2020Assignee: FUJIFILM CorporationInventor: Koudai Fujita

Patent number: 10746993Abstract: Described is a detection device, a head-up display (HUD) and a method for operating a HUD. The detection device, the HUD and the method for operating an HUD are designed to protect an imager of the HUD from damage by incident radiation and to avoid or at least significantly reduce a glare effect of the HUD. The detection device comprises an optical element with a reflecting area and a passband, where the optical transparency of the passband is greater than the optical transparency of the reflecting area. The passband is completely enclosed by the reflecting area, the surface of the passband is smaller than the surface of the reflecting area, and the detection device is optically coupled to the passband. The detection device determines the intensity of a radiation incident on the detection device.Type: GrantFiled: July 13, 2017Date of Patent: August 18, 2020Assignee: Jabil Optics Germany GmbHInventors: Oliver Zeh, Thomas Beyer

Patent number: 10746994Abstract: The technology provides decoupling an aspheric optical element from a birdbath optical element in a near-eye display (NED) device. One or more aspheric lens are used with a spherical birdbath reflective mirror in a projection light engine of a NED device. A projection light engine provides image light (or other information), by way of the spherical birdbath reflective mirror and at least one aspheric lens, to a near-eye display of the NED device. The spherical birdbath reflective mirror collimates and reflects the image light to an exit pupil external to the projection light engine. Decoupling the aspheric optical element from the spherical birdbath reflective mirror may enable high modulation transfer function (MTF) and improved manufacturability of the projection light engine. The NED device having aspheric optical elements decoupled from a birdbath optical element may be positioned by a support structure in a head-mounted display (HMD) or head-up display (HUD).Type: GrantFiled: August 7, 2014Date of Patent: August 18, 2020Assignee: Microsoft Technology Licensing, LLCInventors: Yarn Chee Poon, Joshua A Hudman, R Andrew Wall, Scott McEldowney, Steven John Robbins
