Experimental Study on Temperature Sensing Property for Electroless Ni-Plating Fiber Bragg Grating

In fiber smart metal structures and materials, to gain good bonding between metal material and optical fiber sensor and protect the sensor,the fiber was mentalized by electroless Ni-plating.The property of temperature for electroless Ni-plating fiber Bragg gratings have been studied experimentally.Experimental results show that the Electroless Ni-plating Bragg wavelength of optical fiber grating has good linearity and repeatability with its temperature,The temperature sensitivity of Ni-plating fiber Bragg grating is bigger than bare FBG.Experimental results can provide guidance for farther studying on fiber smart metal structures and materials.
