Paper Abstract

A fiber probe that is capable of two-dimensional traversal scanning is developed and implemented to a time-domain optical coherence tomography (OCT). Due to its geometrical structure, the fiber cantilever of the probe has two intrinsic resonant frequencies. When the probe is base-excited by signal with two mixed frequencies near the resonances, traversal scanning pattern is generated with controllable area coverage through fine tuning of frequency ratio and fetching period. A position sensitive detector is introduced in the probe to record the real-time trajectory of the scanning pattern for image reconstruction. Fast OCT images of samples including rule, coin and leaf are obtained with the developed probe applied to our time-domain OCT setup. We envision obtaining rapid three-dimensional imaging with the developed probe in a Fourier domain OCT system.
