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: An image display system includes an optical subsystem configured to emit a first light beam and a second light beam, wherein the first light beam illuminates a first portion of a composite field of view and the second beam illuminates a second portion of the composite field of view. A scanning mirror is positioned to intercept and reflect the first light beam and the second light beam. The system also has a waveguide with at least one input coupling optical element for receiving the first light beam and the second light beam into the waveguide. The waveguide also has an output coupling optical element for projecting a plurality of output light beams derived from the first light beam and the second light beam from the waveguide to illuminate the composite field of view.

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 the waveguide(s) 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 the waveguide(s) out of the waveguide(s) and direct the light to the camera. The at least one coupling element may include 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 the waveguide(s), the coupling area having an average thickness in a range from 0.1 to 3 millimeters across and/or may have a pinhole sized and/or slit shaped coupling area.

Abstract: A head mounted display system configured to project light to an eye of a user to display augmented reality images can include a frame configured to be supported on a head of the user, a camera disposed temporally on said frame, an eyepiece configured to direct light into said user's eye to display augmented reality image content to the user's vision field, a reflective element disposed on the frame, and at least one VCSEL disposed to illuminate said eye, wherein the camera is disposed with respect to the reflective element such that light from the VCSEL is reflected from the user's eye to the reflective element and is reflected from the reflective element to the camera to form images of the eye that are captured by the camera.

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 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.
