OPTICAL DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240036257 titled 'OPTICAL DEVICE
Simplified Explanation
The abstract describes an optical device for augmented reality or virtual reality displays. It consists of input diffractive optical elements arranged on a waveguide to receive light from a projector. The first input element couples a portion of the light into the waveguide along a first path, while allowing another portion to pass through. The second input element receives the second portion of light and couples a third portion along a second path. An output diffractive optical element then receives light from both paths and directs it towards a viewer at specific positions, creating multiple exit pupils.
- The device uses diffractive optical elements to manipulate light and create a realistic augmented or virtual reality experience.
- It allows light from a projector to be efficiently coupled into a waveguide, reducing loss and improving image quality.
- The device creates multiple exit pupils, allowing multiple viewers to experience the augmented or virtual reality content simultaneously.
Potential applications of this technology:
- Augmented reality headsets: The device can be used in headsets to provide immersive augmented reality experiences, overlaying digital content onto the real world.
- Virtual reality headsets: The device can enhance virtual reality headsets, providing a more realistic and immersive experience by manipulating light and creating multiple exit pupils.
- Gaming and entertainment: This technology can be used in gaming and entertainment systems to create more immersive and interactive experiences for users.
Problems solved by this technology:
- Efficient light coupling: The device solves the problem of efficiently coupling light from a projector into a waveguide, reducing loss and improving image quality.
- Multiple viewer experience: By creating multiple exit pupils, the device allows multiple viewers to simultaneously experience augmented or virtual reality content, enhancing the social aspect of these technologies.
Benefits of this technology:
- Improved image quality: The use of diffractive optical elements helps improve image quality in augmented and virtual reality displays, providing sharper and more realistic visuals.
- Enhanced user experience: By creating multiple exit pupils, the device allows for a more immersive and interactive user experience, making augmented and virtual reality content more engaging.
- Social interaction: The ability to have multiple viewers simultaneously experiencing the content enhances the social aspect of augmented and virtual reality, allowing for shared experiences and collaboration.
Original Abstract Submitted
an optical device for an augmented reality or virtual reality display. a first input diffractive optical element is arranged on a waveguide to receive light from a projector, couple a first portion of the light into the waveguide along a first path, and allow a second portion of the light to pass through. a second input diffractive optical element is arranged to receive the second portion of the light and couple a third portion of the received light along a second path. an output diffractive optical element receives light along the first and second paths and couples the received light out of the waveguide towards a viewer at a first pattern of positions for light along the first path and at a second pattern of positions for light along the second path, providing a first and second plurality of exit pupils corresponding to the first and second pattern of positions.
