Paper Abstract

In this paper, the multi-point hydrogen detection system using the hetero-core optical fiber hydrogen tip sensor based on surface plasmon resonance (SPR) and Pseudorandom Noise code correlation reflectometry (PNCR) has been proposed. This method makes use of the correlation between a launched pseudorandom noise code signal and its reflection, can obtain a high signal to noise ration. We demonstrated the 4 sensors characteristics to 4% hydrogen. It was observed from experimental results that all sensors induced a response time of 15 s for 4% hydrogen for the 25-nm Au / 60-nm Ta2O5 / 5-nm Pd multi-layers film. In addition, all sensors were detected the hydrogen concentration with sufficient sensitivities.
