设计并构造了一种新型内窥镜光学相干断层扫描探头，采用1.9 mm微机电系统（MEMS）电机。新的MEMS内窥镜探头设计消除了从探头近端到远端耦合旋转能量的需要。此外，内窥镜探头的护套和光纤具有比传统内窥镜具有小得多的直径和更柔性的优点，因为不需要加强件来耦合旋转扭矩。在远端，安装在微型马达上的棱镜使光线偏转，以创建横向圆形扫描路径。由于我们的MEMS扫描器不需要旋转单模光纤的耦合，因此可以实现高扫描速度，同时消除由非均匀耦合引起的不稳定光信号。(C)2004年美国光学学会。
A novel endoscopic optical coherence tomography probe was designed and constructed with a 1.9-mm micro-electromechanical system (MEMS) motor. The new MEMS endoscopic probe design eliminates the need to couple the rotational energy from the proximal to the distal end of the probe. Furthermore, the endoscopic probe's sheath and fiber have the advantages of having a much smaller diameter and being more flexible than traditional endoscopes since no reinforcement is needed to couple the rotational torque. At the distal end, a prism mounted on a micromotor deflects the light rays to create a transverse circular-scanning pathway. Because our MEMS scanner does not require the coupling of a rotational single-mode fiber, a high scanning speed is possible while eliminating unstable optical signals caused by nonuniform coupling.
