实验证明了一种基于单模光纤后向散射强度的磁场传感器。利用OTDR系统对光纤端面的反射功率进行了查询，得到了高达1525高斯的磁场变化调制的bb0.2 dB。当用于远程和多路复用配置时，传感器显示相同的响应，证明了这种传感方法的高潜力和多功能性。
A magnetic field sensor based on backscattered intensity of a single mode fiber immersed in a ferrofluid is experimentally demonstrated. An OTDR system is used to interrogate the reflected power at the fiber end face, revealing >2 dB of modulation for magnetic field changes up to 1525 Gauss. The sensor shows the same response when used in remote and multiplexed configurations, demonstrating the high potential and versatility of this sensing approach.
