Abstract

This work presents a forward viewing endoscopic OCT catheter based on a resonant fiber scanning. Two-dimensional optical scanning in a Lissajous pattern was realized by a piezoelectric tube with quartered electrodes and asymmetrically resonant fiber cantilever. Asymmetrically resonant fiber cantilever was assembled by additional fiber fragment and silicon supporting structure to avoid mechanical coupling effect at resonance. The endoscopic catheter of 3.2 mm diameter was assembled and combined with SD-OCT system. Three dimensional images were directly reconstructed by mapping the A-line data sets along non-repeating Lissajous trajectories with high temporal resolution.
