Model-Based Analysis of Reflection-Mode Fiber Hydrogen Sensor

Article Preview

Abstract:

Researchers have successfully prepared reflection-mode hydrogen sensor by coating Palladium (Pd) alloy in the end of the fiber and it has been proved to be in good effect. Characteristics of the hydrogen sensors are influenced by several factors, such as thickness of thin film, substrate, light wavelength and the film material, etc. For best performance, an optical model of reflection-mode fiber hydrogen sensor is established. The effecting law of each factor is analyzed and discussed through model-based simulation method. The results can provide credible design methods for the reflection-mode fiber hydrogen sensor.
