The resonant fiber scanner produces a flying laser spot scan for display or image acquisition purposes. Dynamic nonlinearities during large amplitude vibrations of the resonant fiber scanner result in distortions in the two‐dimensional scan pattern and the acquired images. A dynamic model which includes the fibers dynamic nonlinearities has been developed to understand the nonlinear behavior and as the basis of a controller to remove the scan distortion. A robust state‐space controller has been implemented to force the resonant fiber scanner to follow a spiral scan pattern. Acquired images at 250×250 pixel resolution demonstrate improved image fidelity over previous images taken with open‐loop scanning.
