在许多应用中，嵌入式光纤传感器被认为是结构健康监测的目的。在纤维增强塑料中，嵌入式光纤布拉格光栅被认为是应变监测最流行和最可靠的解决方案之一。尽管它们越来越受欢迎，但用户应该记住它们的缺点，其中许多与嵌入过程有关。本文首先概述了在纤维复合材料中嵌入光纤时需要考虑的一些技术问题。接下来，介绍了一种监测方案，该方案显示了将嵌入的FBG的输出与嵌入的结构的应变联系起来所需的不同步骤。从传感器的嵌入到结构的内部应变测量，该过程的每个步骤已经在文献中单独讨论，而不考虑完整的周期。这篇综述文章总结了文献报道的工作，并试图将其纳入嵌入式光纤布拉格光栅内部应变测量的大图景。最后介绍了光纤布拉格光栅应变原位测量中不可忽视的温度补偿方法。在整个论文中，在适当的地方给出了批评，这应该被视为未来研究的机会。
Embedded optical fibre sensors are considered for structural health monitoring purposes in numerous applications. In fibre reinforced plastics, embedded fibre Bragg gratings are found to be one of the most popular and reliable solutions for strain monitoring. Despite of their growing popularity, users should keep in mind their shortcomings, many of which are associated with the embedding process. This review paper starts with an overview of some of the technical issues to be considered when embedding fibre optics in fibrous composite materials. Next, a monitoring scheme is introduced which shows the different steps necessary to relate the output of an embedded FBG to the strain of the structure in which it is embedded. Each step of the process has already been addressed separately in literature without considering the complete cycle, from embedding of the sensor to the internal strain measurement of the structure. This review paper summarizes the work reported in literature and tries to fit it into the big picture of internal strain measurements with embedded fibre Bragg gratings. The last part of the paper focuses on temperature compensation methods which should not be ignored in terms of in-situ measurement of strains with fibre Bragg gratings. Throughout the paper criticism is given where appropriate, which should be regarded as opportunities for future research.
