摘要

在微创诊断和治疗过程中,需要更小、更灵活的光学成像工具[1]。为此,一种新的图像采集技术已经开发出来,该技术基于波导的可控振动和从波导到物体的光后向散射检测[2]。这项研究的预期结果是创造一种能够在高频率下工作的光学扫描仪,在直径1毫米的外壳中具有大视场(FOV)。该系统的机制已被探索用于近场扫描光学显微镜应用[3],现在正在研究用于扫描光纤内窥镜。本报告讨论了两种可能的波导几何形状的振动特性:圆柱形和锥形光纤。

Mechanical Design and Analysis for a Scanning Fiber Endoscope
There is a need for smaller, more flexible, optical imaging tools for use in minimally invasive diagnostic and therapeutic procedures [1]. Towards this end, a novel technique of image acquisition has been developed based upon the controlled vibration of a waveguide and detection of light backscattered from the waveguide onto an object [2]. The anticipated result of this research is the creation of an optical scanner capable of operating at high frequency, with a large field-of-view (FOV) in a 1 mm diameter enclosure. The mechanics of this system have been explored for use in near-field scanning optical microscopy applications [3], and are now examined for use in a scanning fiber endoscope. Discussed in this report are the vibration characteristics of two possible waveguide geometries: a cylindrical and a tapered optical fiber.
