Publication number: 20240126090Abstract: Head mounted display systems configured to project light to an eye of a user to display augmented reality image content in a vision field of the user are disclosed. In embodiments, the system includes a frame configured to be supported on a head of the user, an image projector configured to project images into the user's eye, a camera coupled to the frame, a waveguide optically coupled to the camera, an optical coupling optical element me, an out-coupling element configured to direct light emitted from the waveguide to the camera, and a first light source configured to direct light to the user's eye through the waveguide. Electronics control the camera to capture images periodically and farther control the first light source to pulse in time with the camera such that light emitted by the light source has a reduced intensity when the camera is not capturing images.Type: ApplicationFiled: October 24, 2023Publication date: April 18, 2024Inventors: Asif Sinay, Barak Freedman, Michael Anthony Klug, Chulwoo Oh, Nizan Meitav
