新型手持式光学相干断层扫描（OCT）探头与聚合物悬臂梁已被开发用于临床口腔和皮肤成像。采用电活性离子聚合物-金属复合悬臂梁，在1 Hz下施加2 V线性交流电压，使光纤产生3 mm的横向扫描运动。低驱动电压确保安全性。两种不同的光学设计实现了向前和侧向扫描，使其能够在人体口腔内的任何地方成像。在体内OCT成像的人的舌头证明。
Novel hand-held optical coherence tomography (OCT) probes with polymer cantilevers have been developed for clinical oral and skin imaging. An electroactive ionic polymer-metal composite cantilever was used to generate 3-mm transverse scanning movement of an optical fiber with applied 2-V linear alternating voltage at 1 Hz. Low driving voltage ensures safety. Two different optical designs achieve both forward and sidewise scanning and make it possible to image everywhere within the human oral cavity. In vivo OCT imaging of the human tongue is demonstrated.
