光纤光栅传感器在海底观测网的应用分析

Analysis of application about fiber grating sensors in the seafloor observatory network

光纤光栅传感器是根据光纤光栅原理发展起来的一种波长调制型光学传感器。海底观测网不仅能实时监控海洋信息,而且还能记录地震和海啸信息。介绍了光纤光栅传感器的特点和海底观测网基本组网结构,分析了光纤光栅传感器应用于海底观测网的优势与不足。

Fiber grating sensors are fiber sensors with the modulation of wavelength based on the fiber grating theory.Seafloor observatory network can not only observe the seafloor in real time,bin： also warn us of the earthquake and tsunami.The feature of fiber grating sensors and basic structure of seafloor observatory net- work are introduced in this paper, analyzed the advantages and disadvantages of application about fiber grating sensors in the seafloor observatory network.
