挫败的弯曲宏的导致的光纤维 cladding 模式总计内部思考效果被用来与单个宏拐弯聚合物的简单结构认识到液体水平探查光纤维循环。测试结果证明扑灭比率到达 1.06 dB。第一洗澡现象不是明显的(大约 0.8%) 。传感器的坚韧性更好,并且反污染的能力与常规传感器相比是更强壮的。做这根察觉到的探针的过程是极其容易的,并且费用是很低的。
The macro-bending induced optical fiber cladding modes frustrated total internal reflection effect is used to realize the liquid level probe with a simple structure of single macro-bend polymer optical fiber loop. The test results show that the extinction ratio reaches 1.06dB. "First bath" phenomenon is not obvious (about 0.8%). The robustness of the sensor is better, and the ability of anti-pollution is stronger compared with the conventional sensors. The process of making this sensing probe is extremely easy, and the cost is very low.
