    Abstract: A waveguide display includes a first diffractive input waveguide operable to receive input data from a first projector and diffract image data associated with the first projector at a first angular offset and a second diffractive input waveguide operable to receive input data from a second projector and diffract image data associated with the second projector at a second angular offset. The waveguide display also includes a diffractive output waveguide optically coupled to the first diffractive input waveguide and the second diffractive input waveguide. The diffractive output waveguide receives the image data associated with the first projector and image data associated with the second projector and is operable to direct image data associated with the first projector toward a first field of view and direct image data associated with the second projector toward a second field of view.

    Abstract: A fiber optic element of a fiber scanning system includes a motion actuator having longitudinal side members, an internal orifice, a first support region, a central region, and a second support region. The fiber optic element also includes a first fiber optic cable passing through the internal orifice and having a first fiber joint as well as a second fiber optic cable passing through the internal orifice. The second fiber optic cable has a second fiber joint disposed in the central region and spliced to the first fiber joint, a second coupling region, a light delivery region, and a light emission tip. The light delivery region is characterized by a first diameter and the light emission tip is characterized by a second diameter less than the first diameter.

    Abstract: An augmented reality system includes a light source configured to generate a virtual light beam. The system also includes a light guiding optical element having an entry portion, an exit portion, and a surface having a diverter disposed adjacent thereto. The light source and the light guiding optical element are configured such that the virtual light beam enters the light guiding optical element through the entry portion, propagates through the light guiding optical element by at least partially reflecting off of the surface, and exits the light guiding optical element through the exit portion. The light guiding optical element is transparent to a first real-world light beam. The diverter is configured to modify a light path of a second real-world light beam at the surface.

    Abstract: A waveguide apparatus includes a planar waveguide and at least one optical diffraction element (DOE) that provides a plurality of optical paths between an exterior and interior of the planar waveguide. A phase profile of the DOE may combine a linear diffraction grating with a circular lens, to shape a wave front and produce beams with desired focus. Waveguide apparati may be assembled to create multiple focal planes. The DOE may have a low diffraction efficiency, and planar waveguides may be transparent when viewed normally, allowing passage of light from an ambient environment (e.g., real world) useful in AR systems. Light may be returned for temporally sequentially passes through the planar waveguide. The DOE(s) may be fixed or may have dynamically adjustable characteristics. An optical coupler system may couple images to the waveguide apparatus from a projector, for instance a biaxially scanning cantilevered optical fiber tip.
