Research Progress in Optical Fiber Magnetic Field Sensor Technology (Invited)
As an important branch of the optical fiber sensing field, optical fiber magnetic field sensors have demonstrated significant application value in various fields owing to their advantages such as small size, remote measurement capability, and easy integration. Their development is closely related to magneto-optical materials. This study focuses on two types of typical magneto-optical materials in recent years: magnetic fluids in the classical field and nitrogen-vacancy centers in diamond in the quantum field. It reviews their research progress in optical fiber magnetic field sensors from the aspects of sensing principles, demodulation methods, structural design, and sensing applications. Finally, the current key challenges are analyzed, and the future research directions and application prospects are prospected.
