Abstract: A fiber scanning system includes an actuator configured to have an actuator natural frequency, and a fiber optic scanning element coupled to the actuator. The fiber optic scanning element is configured to have a fiber natural frequency that is within a threshold of the actuator natural frequency, such that a displacement gain of the fiber optic scanning element as a function of operating frequency exhibits a first peak value at a first resonance frequency less than the fiber natural frequency, and a second peak value at a second resonance frequency greater than the fiber natural frequency.

Abstract: 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.

Abstract: Described are optical fibers and scanning fiber displays comprising optical fibers. The disclosed optical fibers include a plurality of mass adjustment regions, such as gas-filled regions, positioned between a central waveguiding element and an outer periphery for reducing a mass of the optical fiber as compared to an optical fiber lacking the plurality of mass adjustment regions.
