Terfenol-D Based Magnetic Field Sensor With Temperature Independence Incorporating Dual Fiber Bragg Gratings Structure
A magnetic field sensor with temperature insensitivity implemented by two fiber Bragg gratings (FBGs) structure is presented and experimentally demonstrated.In the proposed sensing probe, a Terfenol-D piece is bonded with the same type of two FBGs in different direction relative to magnetic field.Two center wavelengths of the CBN Tincture notches o
