WAFER LEVEL OPTICS FOR VIRTUAL REALITY CAMERAS - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240329405 titled 'WAFER LEVEL OPTICS FOR VIRTUAL REALITY CAMERAS
Simplified Explanation: The patent application describes configurations of projectors and cameras that utilize shared wafer-level optics, where optical elements of both the projector and the camera are fabricated on the same wafer. These projectors and cameras can be integrated into mixed reality headsets, such as AR/VR headsets, or smart glasses.
Key Features and Innovation:
- Projectors and cameras with shared wafer-level optics.
- Integration of projectors and cameras into mixed reality headsets.
- Compact and efficient solution for guiding light in projectors and cameras.
Potential Applications: The technology can be used in:
- Mixed reality headsets
- Smart glasses
- Augmented reality applications
- Virtual reality applications
Problems Solved:
- Bulky and inefficient optical systems in projectors and cameras.
- Lack of integration between projectors and cameras in wearable devices.
Benefits:
- Compact design
- Efficient light guidance
- Enhanced user experience in mixed reality environments
Commercial Applications: Potential commercial applications include:
- Consumer electronics
- Healthcare
- Education
- Entertainment industry
Questions about Shared Wafer-Level Optics: 1. How does the use of shared wafer-level optics improve the integration of projectors and cameras in wearable devices? 2. What are the key advantages of having optical elements of projectors and cameras fabricated on the same wafer?
Original Abstract Submitted
various configurations of projectors and cameras are disclosed that use shared wafer level optics, in which optical elements, e.g., microlenses, of a projector are fabricated on the same wafer as optical elements, e.g., microlenses, of a camera. projectors and cameras can be mounted together on a mixed reality headset, e.g., an ar/vr headset, for example, as a feature of smart glasses. some projectors and/or cameras can be co-located in the arm or temple of the glasses. some projectors and/or cameras can be co-located near a center point of the frame of the glasses. use of shared wafer-level optics provides a compact and efficient solution for simultaneously guiding light leaving a projector and light entering a camera.
