摘要

We propose the two-dimensional scanning probe operating with a single actuator, which is thought useful as a sample probe for optical coherence tomography (OCT). The probe was designed to use a single-body lensed fiber cantilever loaded with an iron-bead and driven by a single-solenoid actuator. Elliptic spiral trace patterns were achieved using off-axis magnetic fields of the solenoid. A three-dimensional OCT image was obtained for a scanning area of 3.8 mm X 3.4 mm at an acquisition speed of 16.7 s/V. Up to 27Hz B-scan rate, the proposed probe worked well, and 1000 A-scans were made per each B-scan.
