摘要
海冰是重要的自然灾害之一,针对静冰压力监测需求,首次提出一种基于光纤Fabry-Perot传感器的静冰压力测试新方法。结合膨胀辅助放电方法,制备了一种薄膜结构的高灵敏度光纤Fabry-Perot压力传感器,并采用金属管/PDMS/AB胶组合方法对传感器进行了封装。在此基础上,研究了–15℃～0℃之间静冰融化和冻结过程中的内部应变变化特性。实验结果表明,所制备的薄膜结构光纤Fabry-Perot压力传感器在静冰压力监测中具有良好的灵敏度。所研究内容对远距离分布式海洋静冰特性监测具有一定的参考价值。
Sea ice is one of the important natural disasters. A new method based on optical fiber Fabry-Perot sensor for ice strain measurement was proposed to meet the needs of ice strain monitoring. A high sensitivity optical fiber Fabry-Perot pressure sensor with thin-film structure was realized by means of pressure assisted arc discharge method, and the sensor was encapsulated by metal tube /PDMS /AB epoxy glue combination method. On this basis, the static internal strain characteristics of ice in the process of melting and freezing during ?15℃~0℃ was studied. Experimental results show that this proposed thin-film fiber Fabry-Perot pressure sensor has good sensitivity characteristic in ice strain monitoring, it is believed of great value for the monitoring of remote distributed sea samples.
