Electroless Nickel Plating and Electroplating on FBG Temperature Sensor


  Metal-coated fiber Bragg grating(FBG)temperature sensors were prepared via electroless nickel(EN)plating and tin electroplating methods on the surface of normal bare FBG.The surface morphologies of the metal-coated layers were observed under a metallographic microscope.The effects of pretreatment sequence,pH value of EN plating solution and current density of electroplating on the performance of the metal-coated layers were analyzed.Meanwhile, the Bragg wavelength shift induced by temperature was monitored by an optical spectrum analyzer.Sensitivity of the metal-coated FBG(MFBG)sensor was almost two times that of normal bare FBG sensor.The measuring temperature of the MFBG sensor could be up to 280°C,which was much better than that of conventional FBG sensor.……
