Abstract

We develop a fast scanning probe for forward-imaging optical coherence tomography (OCT). The probe is based on the resonant oscillation of a fiber cantilever which has two distinguished resonant frequencies intrinsic to its geometry. When actuated by piezoelectric bimorph with signals of mixed frequencies, various two-dimensional traversal scanning patterns are generated. Experiments on different probe parameters relating to the qualities of the final images- such as the density of the scanning coverage, frame rate are carried out. For correct image reconstruction, a micro two-dimensional position-sensitive detector (PSD) is also introduced to record the scanning pattern in real-time. Preliminary results of OCT imaging with this developed probe are presented.
