    摘要: 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.
