Abstract

In this paper, a novel fiber Bragg grating (FBG) temperature sensor system with low cost demodulation mechanism was proposed. The broadband light source was demodulated by a long period fiber grating (LPG) with an appropriate attenuation band. The sensing FBG was encapsulated with aluminum groove to make the FBG have a higher thermal expansion coefficient. The sensor with enhanced sensitivity 0.02°C was realized.
