摘要
光纤光栅传感器除具有一般普通光纤传感器体积小、灵敏度高、带宽宽、抗电磁干扰能力强和耐腐蚀外,还具有易集成、本征自相干性好、波长编码、可实现实时测量和分布式测量等独特优点,近年已成为新型传感及国际智能结构领域中的研究热点.文章介绍了光纤Bragg光栅传感器的基本原理,综述了其在国外船舶结构中的应用,分析了光纤Bragg光栅传感器在信息化智能舰船中能起到的作用和在智能船舶结构中应用的关键技术.
The fiber grating sensor becomes research spot in the field of new type sensors and international intelligent structure because it has not only the same strong points like popular fiber sensors such as small size, high sensitivity, wide bandwidth, strong anti-disturbance and corrosion resistance, but also the unique features of convenient for integrity, good self-pertinence property, wavelength-encoded information, real-time and distributed measurement etc. The paper introduces the principle of fiber Bragg grating sensor and describes their application in the ship structure abroad, as well as analyzes its function in informationized smart ship and key techniques when applied to smart ship structure.
