Two simple techniques for the compensation of the temperature effects in fiber Bragg gratings tuned by magnetostrictive transducers were demonstrated. The Bragg wavelengths were tuned by the magnetic field through the magnetostrictive transducer and two fiber Bragg gratings are arranged in such a way that the magnetostrictive effects on these gratings are added together, while the temperature effects are cancelled. It can reduce the temperature sensitivity of the sensor by more than 10 times, and the additional wavelength shift due to the temperature is only 0.11 nm within the range of 22°C-80°C.
