ANGULAR UNIFORMITY WAVEGUIDE FOR AUGMENTED OR VIRTUAL REALITY - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240210704 titled 'ANGULAR UNIFORMITY WAVEGUIDE FOR AUGMENTED OR VIRTUAL REALITY
The abstract describes a waveguide for use in augmented reality or virtual reality displays, consisting of optical structures in a photonic crystal arranged to create diffractive optical elements that direct light towards a viewer.
- The waveguide includes multiple optical structures in a photonic crystal.
- These structures form diffractive optical elements that manipulate light for display purposes.
- Each diffractive optical element receives light from an input direction and directs it towards the viewer.
- The optical structures have a specific shape with twelve straight sides, each with normal vectors at different angles.
Potential Applications: - Augmented reality headsets - Virtual reality displays - Heads-up displays in vehicles - Medical imaging devices - Military applications for enhanced vision
Problems Solved: - Efficiently directing light towards the viewer in AR/VR displays - Enhancing image quality and clarity - Minimizing optical distortion and aberrations
Benefits: - Improved visual experience in AR/VR environments - Enhanced image resolution and brightness - Compact and lightweight design for wearable devices
Commercial Applications: Title: Advanced Waveguide Technology for AR/VR Displays This technology can be utilized in the development of next-generation AR/VR headsets, medical imaging devices, and military applications, potentially revolutionizing the way we interact with digital information.
Questions about Waveguide Technology: 1. How does this waveguide technology improve the user experience in AR/VR displays? - The waveguide technology enhances image quality and clarity, providing a more immersive and realistic visual experience for users. 2. What sets this waveguide technology apart from traditional optical display methods? - This waveguide technology utilizes diffractive optical elements in a photonic crystal to efficiently direct light towards the viewer, resulting in improved image quality and reduced optical distortions.
Original Abstract Submitted
there is disclosed a waveguide for use in an augmented reality or virtual reality display. the waveguide comprises a plurality of optical structures in a photonic crystal. the plurality of optical structures are arranged in an array to provide at least two diffractive optical elements. 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 respectively have a shape, when viewed in the plane of the waveguide, comprising twelve substantially straight sides, six of the sides having respective normal vectors at a first angle, and the other six of the sides having respective normal vectors at a second angle which is different to the first angle.
