A novel single-mode bend fiber-optic sensing principle is presented. The design makes use of the translucent protective sheath that encases a typical fiber as a means of locating the position of a small bend present on an otherwise straight fiber. We can simultaneously determine bend magnitude by measuring the reduction in the fiber's core light. The theoretical model presented and the experimental results obtained are in excellent agreement, suggesting that a single-point sensor system is feasible with the proposed technique.
提出了一种新型单模弯曲光纤传感原理。该设计利用包裹典型光纤的半透明保护套来确定存在于原本直的光纤上的小弯曲的位置。通过测量光纤纤芯光的衰减，我们可以同时确定弯曲幅度。所提出的理论模型与获得的实验结果高度吻合，表明采用所提出的技术的单点传感器系统是可行的。
