提出了一种基于双相光纤的预浸料结构故障早期检测传感器，并成功地证明了这一点。该传感器由安装在铝板上的蚀刻光纤布拉格光栅（FBG）组成。该传感器使用简单的压力和石化测试台进行测试。通过观察FBG传感器的反射波长的偏移，我们可以同时检测两个参数：（i）压力和（ii）石化。实验结果表明，光纤光栅传感器用于海底石油管道泄漏的早期检测的潜力。(C)2011 Elsevier B.V.保留所有权利。
A dual-phase optical fiber-based sensor for early detection against prepreg structural failures is proposed and successfully demonstrated. The sensor consists of an etched fiber Bragg grating (FBG) mounted onto an aluminium plate. The sensor is tested using a simple pressure and petrochemical test rig. By observing the shift of the reflected wavelength of the FBG sensor we can simultaneously detect two parameters: (i) pressure and (ii) petrochemical. The experimental results show the potential of using the FBG sensor for early detection of submarine oil pipe leaking. (C) 2011 Elsevier B.V. All rights reserved.
