Abstract: 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.

Abstract: A head mounted display system can include a camera, at least one waveguide, at least one coupling optical element that is configured such that light is coupled into said waveguide and guided therein, and at least one out-coupling element. The at least one out-coupling element can be configured to couple light that is guided within said waveguide out of said waveguide and direct said light to said camera. The at least one coupling element may comprise a diffractive optical element having optical power.

Abstract: Augmented reality headgear includes transparent displays that allow a user to simultaneously view the real world and virtual content positioned in the real world and further includes at least one source of coherent light and at least one sensor array for sensing, at a series of times, speckle patterns produced when the coherent light impinges environment surfaces. Circuitry is provided for sensing shifts in the speckle pattern and determining motion which caused the shift of the speckle pattern and adjusting the display of virtual objects displayed by the augmented reality headgear to compensate for the motion.

Abstract: A head mounted display system can include a camera, at least one waveguide, at least one coupling optical element that is configured such that light is coupled into said waveguide and guided therein, and at least one out-coupling element. The at least one out-coupling element can be configured to couple light that is guided within said waveguide out of said waveguide and direct said light to said camera. The at least one coupling element may comprise a diffractive optical element having optical power. Additionally or alternatively, the at least one coupling optical element may have a coupling area for coupling light into said waveguide having an average thickness in a range from 0.1 to 3 millimeters across and/or may have a slit shaped coupling area.

Abstract: A method of tracking movement of an eye of a user includes directing a light beam at the eye. The eye may reflect a portion of the light beam. The method further includes detecting a plurality of speckle patterns formed at a detector by the portion of the light beam reflected by the eye. The plurality of speckle patterns may be detected at a predetermined frame rate. The method further includes tracking movement of the eye by tracking the plurality of speckle patterns from frame to frame.
