A scanning fiber probe is developed to perform two-dimensional (2D) scanning for optical coherence tomography (OCT). The probe exploits resonant oscillations of a fiber cantilever, and asymmetry geometrical structure of the fiber cantilever has two distinguished resonant frequencies along orthogonal directions. Orthogonal resonant oscillations are excited simultaneously and 2D scanning patterns are generated when it is actuated by one piece of piezoelectric bimorph through a driving signal with mixed frequencies near above mentioned resonances. The scanning sampling density crucial to imaging quality can be deliberately controlled by setting of the driving frequencies as well as fetching duration. Fine tuning the driving frequencies within the widths of intrinsic resonant curves of the designed fiber cantilever results in large scanning amplitude with different Lissajous trajectories and thus different scanning coverages are produced. For correct image reconstruction, a 2D position sensitive detector is also introduced in the developed probe to record the scanning pattern simultaneously. With the developed probe to the established OCT system, experiments on typical samples for en-face imaging are carried out at 2 frame/s. Those preliminary imaging results are presented in the paper.
