基于双光栅级联的海洋温度传感研究
Research on Ocean Temperature Sensing Based on Dual-grating Cascading
摘要
Abstract
Ocean temperature is a crucial hydrological parameter that significantly impacts climate change,marine biology,and physical processes.Accurate and long-term monitoring of ocean temperature is essential for understanding ocean thermal conditions and advancing marine technologies.Fiber Bragg grating(FBG)sensors,with their advantages of high precision,sensitivity,corrosion resistance,immunity to electromagnetic interference,ease of integration,and long-term stability,are widely used in ocean temperature monitoring.However,FBG sensors are frequently influenced by strain during operation,giving rise to cross-sensitivity issues.The common challenge is addressed by employing a dual-grating close-distance cascading method to effectively separate temperature and strain parameters through dual-parameter decoupling theoretical simulations and experimental studies.The experimental results demonstrate that the temperature sensitivities of the two FBGs reach 9.38 pm/℃and 9.44 pm/℃,respectively.Additionally,the impact of strain on temperature measurement is quantified,showing that a strain variation of 1 με causes temperature measurement errors of 58.3 mK and 59.7 mK for the two FBGs,respectively.The research results can provide technical support and reference for future fiber optic ocean temperature sensing.关键词
