Publication number: 20250164804Abstract: A head mounted display system configured to project a first image to an eye of a user, the head mounted display system includes at least one waveguide comprising a first major surface, a second major surface opposite the first major surface, and a first edge and a second edge between the first major surface and second major surface. The at least one waveguide also includes a first reflector disposed between the first major surface and the second major surface. The head mounted display system also includes at least one light source disposed closer to the first major surface than the second major surface and a spatial light modulator configured to form a second image and disposed closer to the first major surface than the second major surface, wherein the first reflector is configured to reflect light toward the spatial light modulator.Type: ApplicationFiled: January 17, 2025Publication date: May 22, 2025Applicant: Magic Leap, Inc.Inventors: Kevin Richard Curtis, Bradley Jay Sissom, Hui-Chuan Cheng, Miller Harry Schuck, III, Samarth Bhargava, Erik Heath Arend

Patent number: 12032166Abstract: 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.Type: GrantFiled: January 7, 2022Date of Patent: July 9, 2024Assignee: Magic Leap, Inc.Inventors: Kevin Richard Curtis, Bradley Jay Sissom, Hui-Chuan Cheng, Miller Harry Schuck, III, Samarth Bhargava, Erik Heath Arend

Patent number: 11486826Abstract: 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.Type: GrantFiled: January 24, 2022Date of Patent: November 1, 2022Assignee: Magic Leap, Inc.Inventors: Erik Heath Arend, Volker Zagolla, Carlos Alberto Macias Romero, Bradley Jay Sissom, Miller Harry Schuck, III, Heidi Leising Hall
