The Influence and Research of the Metal-Coated FBG on Temperature Sensitivity
The Fiber Bragg Grating (FBG) sensor’s temperature sensitivity which is influenced by the metal-coated material and thickness was presented. The accurate equation was gotten according to the elasticity and fiber sensor theory. As indicated by the experiment, the changeable curve of the temperature sensitivity between theory equation and experiment is identical. And the FBGs sensitivities can be improved to 3~20 times.
