  • 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.
