摘要： A display subsystem for a virtual image generation system for use by an end user comprises a planar waveguide apparatus, an optical fiber, at least one light source configured for emitting light from a distal end of the optical fiber, and a collimation element mounted to a distal end of the optical fiber for collimating light from the optical fiber. The virtual image generation system further comprises a mechanical drive assembly to which the optical fiber is mounted to the drive assembly. The mechanical drive assembly is configured for displacing the distal end of the optical fiber, along with the collimation element, in accordance with a scan pattern. The virtual image generation system further comprises an optical waveguide input apparatus configured for directing the collimated light from the collimation element down the planar waveguide apparatus, such that the planar waveguide apparatus displays image frames to the end user.

摘要： Architectures are provided for expanding the exit pupil of systems including one or more waveguides. Various embodiments include a display device including one or more waveguides. One or more physical/optical parameters of the one or more waveguides and/or a wavelength of light input to the waveguide can be varied as the angle at which incoming light is incident on the waveguide varies in order to maintain phase correlation between different beamlets of the output light beam emitted from the one or more waveguides.

摘要： A wearable augmented reality head-mounted display system can be configured to pass light from the world forward a wearer wearing the head-mounted system into an eye of the wearer. The head-mounted display system can include an optical display that is configured to output light to form an image. The system may include one or more waveguides that are disposed to receiving the light from the display. A variable power reflector can be disposed on the forward side of the one or more waveguides. The reflector can be configured to have an optical power that is adjustable upon application of an electrical signal.

摘要： A wearable ophthalmic device is disclosed. The device may include an outward facing head-mounted light field camera to receive light from a user's surroundings and to generate numerical light field image data. The device may also include a light field processor to generate modified numerical light field image data by computationally introducing an amount of optical power to the numerical light field image data based on a viewing distance from the user to an object. The device may also include a head-mounted light field display to generate a physical light field corresponding to the modified numerical light field image data.
