一种基于光纤布拉格光栅（FBG）的高性能传感器装置已被开发出来，用于检测小磁场。基于光纤光栅物理长度上光纤周围的智能多层护套，可以轻松检测、分析和评估旋转机器部件、发电机或电力电缆产生的磁场。因此，这种创新的在线非接触式检测方法可以提高高性能机器零件、设备和电缆的质量和可靠性。基本物理原理基于磁致伸缩多层系统，该系统在磁场存在下使高分辨率 FBG 元件发生应变。随后，FBG元件的感应磁场和波长变化之间的固定关系描述了特征灵敏度曲线。已经对该磁场 FBG 传感器的特性进行了深入的测试，并对其性能进行了评估。
A high-performance fiber Bragg grating-based (FBG) sensor device has been developed for the detection of small magnetic fields. Based on a smart multilayer jacket around the fibre over the physical length of the FBG, magnetic fields generated by rotating machine parts, power generators or power cable can be easily detected, analysed and evaluated. Consequently, this innovative, on-line and non-contact inspection method results in an increase in quality and reliability of high-performing machine parts, devices and cables. The basic physical principle is based on a magnetostrictive multilayer system that strains the high-resolution FBG element in presence of magnetic fields. Subsequently, a fixed relationship between induced magnetic field and wavelength change of the FBG element describes the characteristic sensitivity curve. Intensive tests regarding characterisation of this magnetic field FBG sensor have been carried out and its performance has been evaluated.
