  • Patent number: 11378256
    Abstract: In some embodiments, optical systems with a reflector and a lens proximate a light output opening of the reflector provide light output with high spatial uniformity and high efficiency. The reflectors are shaped to provide substantially angularly uniform light output and the lens is configured to transform this angularly uniform light output into spatially uniform light output. The light output may be directed into a spatial light modulator, which modulates the light to project an image.

  • Publication number: 20220206301
    Abstract: An optical system for an augmented reality head mounted display eyepiece that is configured to deliver images to the eye wherein the optical system includes optics. The optics are disposed so as to receive light output from the light source. The optics further arranged with respect to a spatial light modulator such that the light received from the light source passes through the optics and illuminates the spatial light modulator. The light illuminating the spatial light modulator is redirected back through the optics and is coupled into at least one waveguide through at least one in-coupling optical element. At least a portion of the coupled light is ejected from at least one waveguide by at least one out-coupling optical element and directed to the eye of the user.

  • Publication number: 20220146421
    Abstract: A method for determining a residual retardance of an LCOS (Liquid Crystal on Silicon) panel includes transmitting a light beam to the LCOS panel at an angle of incidence and measuring an intensity of a reflected light beam. The method includes biasing the LCOS panel in a dark state and measuring a dark state intensity of the reflected light beam. The method also includes biasing the LCOS panel in a bright state, and measuring a bright state intensity of the reflected light beam. A residual retardance of the LCOS panel is determined based on a contrast ratio of the bright state intensity and the dark state intensity. The method can also include selecting a compensator for the LCOS panel based on the residual retardance.

  • Publication number: 20210231947
    Abstract: An eyepiece for projecting an image includes a first planar waveguide positioned in a first lateral plane. The first planar waveguide comprises a first diffractive optical element (DOE) disposed at a first lateral position. The eyepiece also includes a second planar waveguide positioned in a second lateral plane adjacent to the first lateral plane. The second planar waveguide comprises a second DOE disposed at a second lateral position different from the first lateral position. The eyepiece further includes a third planar waveguide positioned in a third lateral plane adjacent to the second lateral plane. The third planar waveguide comprises a third DOE disposed at a third lateral position different from the first lateral position and the second lateral position. The eyepiece also includes an optical filter positioned between the second planar waveguide and the third planar waveguide. The optical filter is disposed at the third lateral position.

  • Publication number: 20200201026
    Abstract: Techniques for artifact mitigation in an optical system are disclosed. Light associated with a world object is received at the optical system, which is characterized by a world side and a user side. Light associated with a virtual image is projected onto an eyepiece of the optical system, causing a portion of the light associated with the virtual image to propagate toward the user side and light associated with an artifact image to propagate toward the world side. A dimmer of the optical system positioned between the world side and the eyepiece is adjusted to reduce an intensity of the light associated with the artifact image impinging on the dimmer and an intensity of the light associated with the world object impinging on the dimmer.
