We report on recent advances in the use of inexpensive polymer optical fibres (POFs) for sensing applications in avionics. The sensors analysed in this manuscript take advantage of the unique properties of polymers, such as high flexibility, elasticity, and sensitivity, and they range from strain, elongation, and vibration interrogators to level and temperature meters, leading to cost-effective techniques for structural health monitoring in aircraft structures. We also highlight recent power-supply methods using Power-over-POF in order to feed sensors remotely, and we discuss the constraints imposed by connectors on the performance of POF networks in aircrafts.
我们报告了在航空电子设备传感应用中使用廉价聚合物光纤(POF)的最新进展。本手稿中分析的传感器利用了聚合物的独特性能,如高柔韧性、弹性和灵敏度,其范围从应变、伸长和振动探测器到液位和温度计,从而产生了用于飞机结构健康监测的经济高效技术。我们还重点介绍了最近使用基于聚合物光纤的电力传输技术的供电方法,以便远程为传感器供电,并讨论了连接器对飞机中聚合物光纤网络性能的限制。
