本文系统地研究和比较了不同光纤传感器的导波检测方法及其在复合材料层合板损伤检测中的应用。提出了两种光纤传感器，即光纤布拉格光栅（FBG）和基于多普勒效应的光纤（FOD）传感器，并构建了两种类型的导波检测系统。由压电换能器产生的导波传播通过准各向同性碳纤维增强塑料（CFRP）层压板，并获得这些光纤传感器。系统地比较了这几种光纤传感器在超声导波检测中的特点。结果表明，FBG和FOD传感器都可以应用于CFRP层合板的导波和损伤检测。由于FOD传感器和FBG传感器在超声检测中的物理原理不同，FOD传感器采集到的导波信号的信噪比相对较高。此外，FOD传感器对损伤引起的基本剪切水平（SH0）导波敏感，然而，由于FOD传感器在超声检测中是全向的，并且相反，FBG传感器严重依赖于方向，因此不能通过使用FBG传感器来检测该损伤引起的SH0导波。
Guided wave detection using different fiber optic sensors and their applications in damage detection for composite laminates were systematically investigated and compared in this paper. Two types of fiber optic sensors, namely fiber Bragg gratings (FBG) and Doppler effect-based fiber optic (FOD) sensors, were addressed and guided wave detection systems were constructed for both types. Guided waves generated by a piezoelectric transducer were propagated through a quasi-isotropic carbon fiber reinforced plastic (CFRP) laminate and acquired by these fiber optic sensors. Characteristics of these fiber optic sensors in ultrasonic guided wave detection were systematically compared. Results demonstrated that both the FBG and FOD sensors can be applied in guided wave and damage detection for the CFRP laminates. The signal-to-noise ratio (SNR) of guided wave signal captured by an FOD sensor is relatively high in comparison with that of the FBG sensor because of their different physical principles in ultrasonic detection. Further, the FOD sensor is sensitive to the damage-induced fundamental shear horizontal (SH0) guided wave that, however, cannot be detected by using the FBG sensor, because the FOD sensor is omnidirectional in ultrasound detection and, in contrast, the FBG sensor is severely direction dependent.
