Abstract

The main physical quantities in fiber Bragg grating are temperature and strain. The temperature sensors for different materials have been analyzed in this work. The sensing can be possible on the range of Bragg wavelength shifts occurred by the temperature change in the medium. Thus, the temperature is measurement based on the wavelength shifting of the fiber Bragg grating. The mathematical descriptions and simulation of various parameters of FBG temperature sensor are also included in the work.
