  • Publication number: 20180373045
    Abstract: Systems, devices, and methods for optical waveguides that are well-suited for use in wearable heads-up displays (WHUDs) are described. An optical waveguide includes a volume of optically transparent material, a first holographic optical element (HOE) and a second holographic optical element, wherein the first HOE and the second HOE are carried by the volume of optically transparent material, and the first HOE is positioned across a width of the volume of optically transparent material from the second HOE. Light enters the optical waveguide and is propagated down a length of the waveguide by reflection between the first HOE and the second HOE. Propagation of the light within the optical waveguide does not require total internal reflection. The optical waveguide may include means to in-couple the light into the waveguide and means to out-couple the light from the waveguide. WHUDs that employ such optical waveguides are also described.

  • Publication number: 20170184772
    Abstract: A device includes an optical delivery fiber having a core having a first inside diameter joined to a capillary having an outer surface and a capillary tube having an inner surface. The capillary tube has a second inside diameter in the region of the joining to the optical delivery fiber. The second inside diameter is less than the first inside diameter of the delivery fiber.

  • Publication number: 20080231737
    Abstract: A sensor includes control circuitry and a pixel having a photo site, a first storage node and a second storage node. The control circuitry operates to transfer a first collected signal produced by light from a first image from the photo site to the first storage node during a first period, to transfer a second collected signal produced by light from a second image from the photo site to the second storage node during a second period that follows the first period and to transfer the first and second collected signals out of the pixel during a third period that follows the second period. The first storage node includes a first capacitor and a first reset gate coupled directly between the first capacitor and a reset voltage. The second storage node includes a second capacitor and a second reset gate coupled directly between the second capacitor and the reset voltage.

  • Patent number: 7176967
    Abstract: A camera includes a first sensor disposed to image light that propagates along a reflected axis, a second sensor disposed to image light that propagates along a direct axis, and a rotatable structure disposed to define a rotation plane that is oblique to both the reflected axis and the direct axis. The rotatable structure includes either a first transmission sector, a first reflection sector disposed adjacent to the first transmission sector, a second transmission sector disposed adjacent to the first reflection sector and a second reflection sector disposed adjacent to the second transmission sector or the rotatable structure includes a first reflection sector, a first opaque sector disposed adjacent to the first reflection sector, and a first transmission sector disposed adjacent to the first opaque sector.

  • Patent number: 6904198
    Abstract: An optical source is provided to the side of a fiber. The fiber is a single mode fiber which has a core and a cladding. The Bragg grating is written into the core at a low angle. Light emitted from the optical source is index-match coupled into the cladding by using an index matched element. Then, light is coupled into the fiber core along its length.

  • Patent number: 6891926
    Abstract: An apparatus includes a sensor and a bundle of optical fibers. The bundle of optical fibers has a first end and a second end. The bundle of optical fibers at the first end extends in a first fiber direction and defines a first section plane that is normal to the first fiber direction. The first end defines a first end plane that is obliquely oriented with respect to the first section plane. The bundle of optical fibers at the second end extends in a second fiber direction and defines a second section plane that is normal to the second fiber direction. The second end defines a second end plane that is obliquely oriented with respect to the second section plane. The sensor is disposed in a confronting relation with the second end.

  • Patent number: 5729017
    Abstract: The specification describes pulse generators and detectors for the far infra-red and operating at frequencies of the order of 10.sup.10 to 10.sup.13 Hz (the Terahertz range). These devices rely on electric field interactions with optical beams in biased metal semiconductor microstructures. The electric field is created between metal electrodes on the semiconductor surface and the electric field is enhanced, according to the invention, by configuring the electrode gap geometry with sharp electrode features.
