  • Patent number: 11237332
    Abstract: An optical apparatus includes an optically transparent slab waveguide including first and second, mutually-parallel planar faces and an edge non-parallel to the planar faces. A radiation source directs a beam of optical radiation to enter the waveguide through the first planar face at an entrance location and entrance angle selected so that the beam subsequently exits the waveguide at an exit location in a surface selected from among the second planar face and the edge. A scanning mirror is positioned to receive the beam that has exited through the surface and to reflect the beam back through the surface into the waveguide while the scanning mirror rotates about an axis parallel to the surface over a range of angles selected so as to cause the beam, after reflection back into the waveguide through the surface, to propagate within the waveguide by total internal reflection (TIR).

  • Patent number: 10459327
    Abstract: A compact head-up display for a vehicle includes: an image generator that displays an image on a display surface, and a semi-reflecting optical element, arranged at a distance from the image generator, that forms, on a first side of the optical element, a virtual image. The virtual image is visible from a viewing window on a second side of the optical element. The display includes an optical component that lengthens the optical path of the image passing from the image generator to the optical element. The optical component includes one entry face and one exit face, and a first reflecting face and a second reflecting face. The first reflecting face reflects the image from the entry face toward the second reflecting face. The second reflecting face reflects the image from the first reflecting face toward the exit face. The entry face is in contact with the display surface.

  • Patent number: 10394027
    Abstract: A head-up display system includes an image-forming and projection device, a combiner, a housing, and a lid body. The lid body includes at least a first divided lid body and a second divided lid body which engage with each other at the time of covering an opening of the housing. The first divided lid body includes an optical path regulator that regulates an optical path of projection light of a display image projected from the image-forming and projection device in use of the combiner onto an inner side of the housing, and allows projection light, which is necessary for formation of the virtual image of the display image in the projection light of the display image, to pass through the optical path regulator. The second divided lid body includes a covering member that covers the optical path regulator at the time of covering the opening.

  • Patent number: 10310268
    Abstract: An apparatus, for use in replicating an image associated with an input-pupil to an output-pupil, comprises an optical waveguide including a bulk-substrate, an input-coupler and an output-coupler. The bulk-substrate includes first and second major sides and peripheral sides. The input-coupler couples, into the waveguide, light corresponding to the image associated with the input-pupil. The output-coupler couples, out of the waveguide, light corresponding to the image that has traveled through the waveguide from the input-coupler to the output-coupler at least in part by way of TIR. At least one of the peripheral sides includes first and second surfaces that define first and second planes angled 45 degrees relative to one another. Such a peripheral side provides for effective recycling of light that would otherwise leak out of the waveguide through the peripheral side.

  • Patent number: 10146054
    Abstract: An eyepiece for a head wearable display includes a curved lightguide component, a curved see-through component, an output coupler, and a prescription layer. The curved lightguide component guides display light received at an input region and releases the display light along an eye-ward direction in a viewing region. The output coupler is disposed at the viewing region to redirect the display light towards the eye-ward direction for output from the curved lightguide component. The output coupler is at least partially transmissive to ambient light incident through a world-facing side such that the viewing region is see-through. The curved see-through component is mated to the world-facing side of the curved lightguide component. The prescription layer has a first side mated to an eye-facing side of the curved lightguide component and a second side having a curvature that introduces prescriptive lensing to both the ambient light and the display light.
