LIGHTGUIDE WITH POLARIZATION-SELECTIVE BULK REFLECTORS - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240210611 titled 'LIGHTGUIDE WITH POLARIZATION-SELECTIVE BULK REFLECTORS
Simplified Explanation:
This patent application describes a lightguide with partially reflective slanted polarization-selective bulk mirrors that can be used in a near-eye display with a polarized image source. The mirrors reflect light of the polarized image source while fully transmitting light of the orthogonal polarization, making them less noticeable to external viewers while maintaining high efficiency in delivering the image light to the viewer.
Key Features and Innovation:
- Lightguide with partially reflective slanted polarization-selective bulk mirrors
- Designed for near-eye displays with polarized image sources
- Mirrors reflect light of the polarized image source and transmit light of the orthogonal polarization
- Enhances efficiency of delivering image light to the viewer
- Reduces visibility of mirrors to external viewers
Potential Applications: The technology can be used in:
- Augmented reality headsets
- Virtual reality headsets
- Heads-up displays in vehicles
- Medical imaging devices
- Military applications
Problems Solved:
- Reduced visibility of bulk mirrors in near-eye displays
- Improved efficiency in delivering image light to the viewer
- Enhanced user experience in viewing polarized images

Original Abstract Submitted
a lightguide with partially reflective slanted polarization-selective bulk mirrors is disclosed. the lightguide may be used in a near-eye display with a polarized image source. the polarization-selective bulk mirrors reflect light of the polarized image source, and fully transmit light of the orthogonal polarization, causing the mirrors to be less conspicuous to an external viewer while preserving high efficiency of delivery of the image light to the viewer.
