Fiber Optic Magnetic Sensor Testing

Home / Fiber Optic Magnetic Sensor Testing

Several scalar and vector magnetometers have been proposed in the recent past by exploiting the coating of magneto-optical materials like yttrium iron garnet, silk fibroin hydrogel, Fe 3 O 4 /NiFe 2 O 4 plasmons, magnetostrictive materials like Trefenol-D, etc. Fiber-optic magnetic field sensors have garnered considerable attention in the field of marine monitoring due to their compact size, robust anti-electromagnetic interference capabilities, corrosion resistance, high sensitivity, ease of multiplexing and integration, and potential for large-scale.
