【摘要】 本文首先阐述了光纤布拉格光栅(FBG)传感系统的传感原理和基本组成。然后介绍了我们研制的FBG温度和应变传感器的特性以及关于它们应用于平台监测中的可靠性问题的研究结果,包括疲劳损伤、防水密封和机械防护。最后讨论了FBG传感系统在海洋工程中的其它潜在用途。更多还原

【Abstract】 Sensing mechanism of Fiber Bragg gratings (FBGs) and its sensing system are presented. Then ,theperformance of the FBG strain and temperature sensors we designed is described. Some results related to thereliability of the FBG sensor in the application to monitoring offshore platforms is also given, whichinvolves fatigue damage, waterproof packing and mechanical protection. Finally, other potential applicationsof FBGs in offshore engineering are discussed.更多还原
