AUGMENTED REALITY DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 17967568 titled 'AUGMENTED REALITY DEVICE

Simplified Explanation

The abstract describes an augmented reality (AR) device that includes a display, a polarization-conversion reflector, a waveguide, an input-coupler, and an output-coupler.

  • The display outputs light of a first polarization.
  • The polarization-conversion reflector converts the light of the first polarization into light of a second polarization that is orthogonal to the first polarization and reflects it.
  • The waveguide is a flat plate shape with a surface inclined with respect to the optical axis of the light output from the display.
  • The side of the waveguide is positioned between the display and the polarization-conversion reflector.
  • The input-coupler inputs the light of the second polarization into the waveguide.
  • The output-coupler outputs the light propagating in the waveguide.

Potential applications of this technology:

  • Augmented reality devices and headsets
  • Virtual reality devices
  • Gaming and entertainment industry
  • Medical and healthcare applications
  • Industrial and manufacturing applications

Problems solved by this technology:

  • Efficiently converting and reflecting light of different polarizations
  • Providing a compact and lightweight design for AR devices
  • Enhancing the visual quality and clarity of AR content

Benefits of this technology:

  • Improved user experience with augmented reality content
  • Enhanced image quality and brightness
  • Reduced weight and size of AR devices
  • Increased efficiency and performance of AR displays


Original Abstract Submitted

An augmented reality (AR) device is provided. The AR device includes a display configured to output light of a first polarization; a polarization-conversion reflector provided opposite to an output side of the display, the polarization-conversion reflector converting the light of the first polarization into light of a second polarization that is orthogonal to the first polarization and reflect the light of the second polarization; a waveguide having a flat plate shape, a normal line of a flat surface of the flat plate shape being inclined with respect to an optical axis of the light of the first polarization output from the display, a side of the waveguide being provided between the display and the polarization-conversion reflector; an input-coupler inputting the light of the second polarization into the waveguide; and an output-coupler outputting light propagating in the waveguide.
