| 摘 要： | 基于压电换能器技术设计了一种应用于光学相干层析成像的新型内窥式二维光纤扫描探头,即利用两片压电陶瓷片和一片薄导电基片驱动光纤探头.该探头利用光纤悬臂的共振特性,通过对压电陶瓷施加等于光纤共振频率的混频信号,能同时激发光纤悬臂两正交方向上的振动,可以实现光纤悬臂的二维扫描.建立了理论模型并进行了有限元仿真分析,最后搭建了...

| Abstract: | An endoscope scanning fiber probe was designed to perform two-dimensional(2D) scanning for optical coherence tomography based on the PZT.Two piezoelectric ceramic and a thin conductive substrate were used to drive the optical fiber probe.The probe used the cantilever resonance of optical fiber cantilever,imposed the mixing signals which closed to the resonant frequency of optical fiber on the piezoelectric ceramic,and also stimulated two orthogonal directions vibration of fiber cantilever to achieve two-dim... |
