CURVED LIGHTGUIDE IN A SEE-THROUGH SHELL - A simplified explanation of the abstract
This abstract first appeared for US patent application 18130601 titled 'CURVED LIGHTGUIDE IN A SEE-THROUGH SHELL
The abstract describes a head-mounted display with a unique lens design and light engine.
- The eyeglasses frame houses the lens and light engine.
- The lens has a world-facing spherical surface and an eye-facing surface, with a curved lightguide inside.
- The curved lightguide includes an incoupler surface, a first freeform surface facing the world-facing surface, and a second freeform surface facing the eye-facing surface.
- Low refractive index regions are present between the freeform surfaces and conformal freeform surfaces of the optical shell.
Potential Applications: - Virtual reality and augmented reality headsets - Medical imaging devices - Military and defense technology - Gaming peripherals - Training and simulation equipment
Problems Solved: - Enhanced optical performance - Improved image quality - Reduced weight and size of the display - Increased comfort for users - Enhanced user experience in immersive environments
Benefits: - Crisp and clear visuals - Compact and lightweight design - Comfortable to wear for extended periods - Immersive and realistic viewing experience - Versatile applications in various industries
Commercial Applications: The technology can be used in the development of advanced virtual reality headsets for gaming, medical imaging devices for healthcare professionals, and military training simulations. It has the potential to revolutionize the way we interact with digital content and immersive environments.
Questions about the technology: 1. How does the curved lightguide inside the lens improve optical performance? 2. What are the specific advantages of having low refractive index regions in the lens design?
Original Abstract Submitted
A head mounted display includes an eyeglasses frame, a lens framed in the eyeglasses frame, and a light engine disposed in the eyeglasses frame. The lens includes an optical shell comprising a world-facing spherical surface and an opposing eye-facing surface and a curved lightguide disposed in the optical shell. The curved lightguide includes an incoupler surface, a first freeform surface facing the world-facing spherical surface, and a second freeform surface facing the eye-facing surface. The lens further includes a first low refractive index region disposed between the first freeform surface and a first conformal freeform surface of the optical shell and a second low refractive index region disposed between the second freeform surface and a second conformal freeform surface of the optical shell.
