  • Patent number: 11860366
    Abstract: A system comprising an illumination system to direct light from one or more light sources to a limiting output pupil of a projection optomechanical system, a liquid crystal on silicon display panel (LCOS) to modulate the light from the projection optomechanical system and to direct the modulated light back toward the projection optomechanical system, and an in-coupler to a combiner waveguide to receive the modulated light from the LCOS, after it passes through the projection optomechanical system. The system in one embodiment is designed so that the light that passes through the projection optomechanical system from the illumination system lands on the LCOS within the limiting output pupil of the projection optomechanical system.

  • Publication number: 20170139209
    Abstract: A system (100), method (900), and apparatus (110) for displaying an image (880). The system (100) can use a curved mirror (420) in conjunction with a partially transparent plate (430) to project an image directly on the eyes (92) of a user (90). The curved mirror (420) and plate (430) combination can also be used for additional functions in a VRD visor apparatus (116) such as the ability to operate in a tracking mode (123) where the eyes (92) of the viewer (96) are tracked and the ability to operate in in augmentation mode (122) where the viewer (96) can see the displayed image (880) overlaying a view of their physical environment (650).
