近年来，光纤传感器的重要性日益增加，并且在工业应用的许多领域中得到了很好的应用。本文介绍了自诊断光纤传感器的概念。提出的传感器是为了解决复杂结构中的嵌入式光纤传感器的问题，并使在操作条件下的验证。为此，开发了不同的磁致伸缩涂层光纤传感器，并进行了各种实验，以验证其操作模式，并确定各自的再现性。的测量原理说明所获得的实验结果，其中示出了在0.25 mT的磁场强度变化的波长从1 pm的变化。此外，实施磁致伸缩传感器的温度特性进行了分析，并确定了一个实验因子为1.5相比，参考光纤传感器。
Fiber optic sensors have gained increasing importance in recent years and are well established in many areas of industrial applications. In this paper, we introduce a concept of a self-diagnostic fiber optic sensor. The presented sensor is to resolve the problems of embedded fiber optic sensors in complex structures and to enable the validation under operational conditions. For this purpose, different magnetostrictive coated fiber optic sensors were developed and various experiments were performed to verify their mode of operation and to determine the respective reproducibility. The measuring principle is illustrated by obtained experimental results, which showed a change in wavelength from 1 pm at a magnetic field strength change of 0.25 mT. In addition, the temperature characteristics of the implemented magnetostrictive sensor were analyzed and an experimental factor of 1.5 compared to a reference fiber optic sensor was determined.
