  • Publication number: 20230026078
    Abstract: Systems and methods for tracking the position of a head-mounted display (HMD) system component. The HMD component may carry a plurality of angle sensitive detectors that are able to detect the angle of light emitted from a light source. The HMD component may include one or more scatter detectors that detect whether light has been scattered or reflected, so such light can be ignored. Control circuitry causes light sources to emit light according a specified pattern, and receives sensor data from the plurality of angle sensitive detectors. The processor may process the sensor data and scatter detector data, for example using machine learning or other techniques, to track a position of the HMD component. An angle sensitive detector may include a spatially-varying polarizer having a position-varying polarizing pattern and one or more polarizer layers that together are operative to detect the angle of impinging light.

  • Patent number: 11487120
    Abstract: The present disclosure relates generally to techniques for improving the performance and efficiency of optical systems, such as optical systems for using head-mounted display system. The optical systems of the present disclosure may include polarized catadioptric optics, or “pancake optics,” which utilize a wire grid polarizer as a reflective polarizer. Wire grid polarizers may not perform uniformly over wavelength or over varying angles of incidence. To improve performance, a spatially varying polarizer is provided in the optical system that operates to provide polarization compensation for the wire grid polarizer so that the wire grid polarizer performs more uniformly over wavelength and/or over incidence angles (e.g., on-axis and off-axis). The spatially varying polarizer may be formed of a liquid crystal material, such as a multi-twist retarder.

  • Patent number: 11467444
    Abstract: Systems and methods for providing a polarization recycling structure for use in applications, such as display systems that include a liquid crystal display assembly. The polarization recycling structure may include a first spatially varying polarizer spaced apart from a second spatially varying polarizer.
