Abstract :
This paper studies the temperature dependence of the performance in magnetostrictive fiber-optic Michelson interferometric magnetic field sensors. Experiments are carried out and the results show that the sensor system output, system sensitivity and transducer´s mechanical resonant frequency are strongly affected by the ambient temperature. Fitted expressions are provided and compensation methods are demonstrated with experimental verification.
