| Abstract: | A novel all-fiber methane detection system was constructed.In this work,it is proposed a novel optical fiber gas sensor based on cascade of hollow-core photonic bandgap fibers(PBF).Harmonic detectin was used as signal processing method.The diffusion of gas inside of the hollow core is analysed and the optimal design of sensing gas cell is completed.The feasibility of the sensor for methane detection is verified by experements. |
