The surface plasma resonance fiber optic sensor has its research values in theory and will be widely applied in engineering because of its simple structure and high sensitivity. It's a simple and sensitive method to measure refractive index with optical fiber surface plasma wave. We make use of this characteristic to manufacture the surface plasma resonance fiber optic sensor which can monitor the cure of composite material by detecting the refractive index. One fiber optic sensing probe which has reliable performance and is convenient to operate for detecting the refractive index has been designed. A system for detecting the solution refractive index has been developed and several solutions whose refractive indices are known and different are tested with this system. The result shows that this system is credible and stable and the parameters tested are accordant with the practical situation.
