  • Patent number: 12111482
    Abstract: An optical device for augmented reality includes an optical means for transmitting at least part of visible light therethrough, a reflective unit disposed inside the optical means, and an image output unit configured to output image light corresponding to an image for augmented reality toward the inner surface of the optical means. The image light corresponding to the image for augmented reality output from the image output unit is reflected at least once from the inner surface of the optical means and transferred to the reflective unit. The reflective unit reflects the transferred image light toward the pupil of an eye of a user, thereby providing the image for augmented reality to the user.

  • Patent number: 12105289
    Abstract: A display system includes a waveguide assembly having a plurality of waveguides, each waveguide associated with an in-coupling optical element configured to in-couple light into the associated waveguide. A projector outputs light from one or more spatially-separated pupils, and at least one of the pupils outputs light of two different ranges of wavelengths. The in-coupling optical elements for two or more waveguides are inline, e.g. vertically aligned, with each other so that the in-coupling optical elements are in the path of light of the two different ranges of wavelengths. The in-coupling optical element of a first waveguide selectively in-couples light of one range of wavelengths into the waveguide, while the in-coupling optical element of a second waveguide selectively in-couples light of another range of wavelengths. Absorptive color filters are provided forward of an in-coupling optical element to limit the propagation of undesired wavelengths of light to that in-coupling optical element.

  • Patent number: 12057242
    Abstract: A trap for quantum particles, e.g., cesium atoms, is formed using electromagnetic radiation (EMR) of different wavelengths (concurrently and/or at different times). “Red-detuned” EMR, having a trap wavelength longer than a resonant wavelength for a quantum particle is “attracting” and, so, can be used to form the array trap while loading atoms into the array trap. “Blue-detuned” EMR, having a trap wavelength shorter than the resonant wavelength can repel atoms into dark areas away from the EMR peaks so that the atoms are not disturbed by interference carried by the EMR; accordingly, the blue-detuned EMR is used to form the array trap during quantum-circuit execution. Red and blue detuned EMR are used together to form deeper traps that can be used to detect vacant atom sites. Other combinations of trap wavelengths can also be used.

    Abstract: An optical imaging film includes: a focusing layer, having two or more focusing structures; and a graphic layer, having two or more sub-graphics, and at least part of the sub-graphics are configured as a partial pattern of a preset graphic. The focusing layer is adapted to the graphic layer, and the focusing structures are provided corresponding to the sub-graphics, such that the optical imaging film presents an image of the preset graphic with a magnifying effect. The graphic layer of the optical imaging film includes a plurality of sub-graphics, and each of the plurality of the sub-graphics interacts with the corresponding focusing structure to form an image with a magnifying effect. Therefore, the sub-graphic is relatively large, thereby increasing the size of the images. That is, the optical imaging film can increase the magnification of the preset graphic.
