WAVEGUIDE FOR AUGMENTED REALITY OR VIRTUAL REALITY DISPLAY - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240045205 titled 'WAVEGUIDE FOR AUGMENTED REALITY OR VIRTUAL REALITY DISPLAY
Simplified Explanation
The patent application describes a waveguide for use in augmented reality or virtual reality displays. The waveguide includes multiple optical structures arranged in an array on a photonic crystal. Two diffractive optical elements are overlaid on each other within the waveguide. Each element receives light from an input direction and couples it towards the other element, which acts as an output diffractive optical element. The optical structures have different cross-sectional shapes at different positions in the array, providing different diffraction efficiencies.
- The waveguide is designed for use in augmented reality or virtual reality displays.
- It includes multiple optical structures arranged in an array on a photonic crystal.
- Two diffractive optical elements are overlaid on each other within the waveguide.
- Each element receives light from an input direction and couples it towards the other element.
- The other element acts as an output diffractive optical element, providing outcoupled orders towards a viewer.
- The optical structures have different cross-sectional shapes at different positions in the array.
- This provides different diffraction efficiencies at different positions in the array.
Potential Applications:
- Augmented reality displays
- Virtual reality displays
Problems Solved:
- Enhances the performance of waveguides in augmented reality or virtual reality displays
- Improves the efficiency of light coupling and outcoupling in waveguides
Benefits:
- Improved image quality in augmented reality or virtual reality displays
- Enhanced user experience with clearer and more realistic visuals
- Increased efficiency and effectiveness of waveguide technology
Original Abstract Submitted
a waveguide for use in an augmented reality or virtual reality display comprises a plurality of optical structures in or on a photonic crystal. the plurality of optical structures are arranged in an array to provide two diffractive optical elements overlaid on one another in the waveguide. each of the two diffractive optical elements is configured to receive light from an input direction and couple it towards the other diffractive optical element which can then act as an output diffractive optical element, providing outcoupled orders towards a viewer. the plurality of optical structures have different respective cross sectional shapes, for a cross section parallel to the plane of the waveguide, at different positions in the array in order to provide different diffraction efficiencies at different positions in the array.
