Paper Abstract

The novel FBG temperature sensor eliminating lateral strain cross-sensitivity was present and theoretically analyzed. The temperature sensor characteristic of the FBG based on the method for eliminating lateral strain was researched from room temperature to 190°C, and the FBG was pressed by lateral force during rising temperature. The lateral force resulted in the birefringence of the FBG, and the FBG exited two different reflective spectra meeting with the Bragg condition. The change spacing of the peak value between two reflective spectra is used to eliminate lateral strain crosssensitivity to temperature, and amend the temperature sensitivity coefficient and the change temperature value.
