Abstract

The present work investigates reflectivity of reflective surface for optical fiber hydrogen sensor. High reflectivity and low light scattering of multilayer electrolyte reflective membrane in two optical paths could increase signal to noise ratio of hydrogen sensor, and provide longer operational lifetime for hydrogen sensor. When the multi-layer electrolyte total reflection membrane was made up of TiO₂ and SiO₂, it was found that the reflectivity of membrane could reach almost 100% through a series of simulation experiments, the design of multilayer electrolyte reflective membrane benefits to the subsequent weak signal processing for optical fiber hydrogen sensor.
