摘要： A display assembly suitable for use with a virtual or augmented reality headset is described and includes the following: an input coupling grating; a scanning mirror configured to rotate about two or more different axes of rotation; an optical element; and optical fibers, each of which have a light emitting end disposed between the input coupling grating and the scanning mirror and oriented such that light emitted from the light emitting end is refracted through at least a portion of the optical element, reflected off the scanning mirror, refracted back through the optical element and into the input coupling grating. The scanning mirror can be built upon a MEMS type architecture.

摘要： A waveguide display system may include an eyepiece waveguide that can have a first surface and a second surface, the waveguide including an incoupling diffractive optical element (DOE) and an outcoupling DOE. The waveguide display system may include a light source and a scanning mirror, and may include reflective and collimating optical elements. The incoupling DOE can be configured to selectively propagate incident light beams to the outcoupling DOE in the waveguide through total internal reflection (TIR).

摘要： A method of operating a multi-axis fiber scanner having a base including a base plane includes providing a source of electromagnetic radiation, directing the electromagnetic radiation through a fiber link that passes through the base plane of the base along a longitudinal axis orthogonal to the base plane, and supporting a retention collar positioned a distance from the base plane. The method also includes actuating a first piezoelectric actuator among a plurality of piezoelectric actuators to decrease the distance between a first side of the base and the retention collar, actuating a second piezoelectric actuator among the plurality of piezoelectric actuators to increase the distance between a second side of the base and the retention collar, and scanning the fiber link in a scanning plane.

摘要： 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.

摘要： A method of rendering virtual content comprises capturing an image of a field of view of a user, extracting a set of map points based on the captured image, recognizing an object based on the extracted set of map points, retrieving semantic data associated with the recognized object and attaching the semantic data to object data associated with the recognized object, and inserting the recognized object data and the semantic data attached thereto into a virtual world model such that virtual content, when rendered at a user device of the user, is displayed in relation to the recognized object.

摘要： 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.
