Abstract:An optical fiber Sagnac magnetic field sensor based on magnetic fluid is proposed.The magnetic fluid exhibits magneto-optic birefringence under external magnetic field,in which the nanoparticles form chains along the magnetic field and cause the anisotropy.The interference spectrum of the sensor shifts with the external magnetic field due to the magnetic fluid film inserted in the Sagnac loop together with a section of polarization maintaining fiber.The output spectrum shifts with the variation of magnetic ...
Keywords:fiber optics  optical fiber magnetic field sensor  Sagnac interferometer  magnetic fluid  magneto-optic effect  birefringence
