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 × 3.4 mm at an acquisition speed of 16.7 s/V. Up to 27 Hz B-scan rate, the proposed probe worked well, and 1000 A-scans were made per each B-scan.
我们提出了一种二维扫描探针,它使用单个执行器操作,被认为是光学相干断层扫描(OCT)的一种有用的样品探针。该探针设计为使用带有铁珠的单个体透镜光纤悬臂,并由单个螺线管致动器驱动。使用螺线管的离轴磁场实现了椭圆螺旋轨迹图案。在 16.7 s/V 的采集速度下,获得了 3.8 mm×3.4 mm 的扫描区域的三维 OCT 图像。在高达 27 Hz 的 B 扫描速率下,该探头工作良好,每次 B 扫描进行 1000 次 A 扫描。
