BAE Systems had 12 patents in metaverse during Q4 2023. The waveguide assembly described in the patent allows for the enlargement of pupil size of image-bearing light in two different axes using first and second waveguide slabs. The second waveguide slab enables the user to view real world imagery and image-bearing light simultaneously through diffractive in-coupling and out-coupling regions.

Application: Waveguide assembly (Patent ID: US20230333383A1)
The patent filed by BAE Systems Plc describes a waveguide assembly that includes two waveguide slabs to receive and enlarge image-bearing light, allowing a user to view real-world imagery and the out-coupled light simultaneously. The first waveguide slab enlarges the pupil size of the light parallel to a first axis, while the second waveguide slab further enlarges the pupil size parallel to a second axis orthogonal to the first. The assembly utilizes total internal reflection (TIR) and diffractive elements for coupling and decoupling the light, enhancing the user's viewing experience.
Additionally, the patent includes claims for a binocular arrangement and head-mounted display using the described waveguide assembly. The binocular arrangement provides separate images to each eye of the user, while the head-mounted display enlarges the pupil size of image-bearing light for immersive viewing. These applications, including augmented reality glasses, leverage the unique features of the waveguide assembly to enhance the user's visual experience in various scenarios.
