摘要： Described herein are embodiments of fiber scanning systems and methods of scanning optical fibers. The disclosed systems and methods advantageously provide an improvement to the scanning range, the oscillation amplitude, and/or the maximum pointing angle for an optical fiber in a fiber scanning system by inducing a buckling of a portion of the optical fiber.

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： The invention relates to a method of fabricating a shaped fiber, the method comprising: covering a portion of a fiber optic cable with an etch jacket to define an exposed region of the fiber optic cable and a covered region of the fiber optic cable; exposing the exposed region of the fiber optic cable and the etch jacket to an etchant solution; removing at least a portion of the exposed region of the fiber optic cable in response to exposure to the etchant solution; and wicking the etchant solution under at least a portion of the etch jacket to remove at least a portion of the covered region of the fiber optic cable. The method can include fabricating a tapered fiber emission tip by etching a portion of an emission region to form successively deeper etch profiles.

摘要： An eye tracking system (600) comprising: a pair of glasses (210); a light scanning projector (620) coupled to the pair of glasses and operable to scan a beam of light; an eyepiece (630) mounted in one of the two frames (212) and optically coupled to the light scanning projector (620); one or more photodetectors (640) coupled to at least one of the two frames (212) of the pair of glasses (210) and operable to detect a first set of time-varying reflected signals associated with a first series of pixels and a second set of time-varying reflected signals associated with a second series of pixels projected by the light scanning projector (620); and a processor (610) operable to determine an eye orientation based on a correlation between the first set of time-varying reflected signals and the first series of pixels and a correlation between the second set of time-varying reflected signals and the second series of pixels.
