The fiber grating sensor is a novel sensor and has many strong points to the old sensor, such as small size, high sensitivity, high temperature resistance and corrosion resistance, strong anti-disturbance of electromagnetism, and can form a large scale distributed sensor net. So it becomes research spot in the field of structure health monitoring. This paper introduces the characteristics and the theory of fiber Bragg grating sensor. Review the development and applications of fiber Bragg grating sensor on ship structure health monitoring. Discuss the compose of ship structure health monitoring and the key content of studying.%光纤光栅传感器是一种新型传感器，相对传统的传感器具有体积小、灵敏度高、耐高温、耐腐蚀、抗电磁干扰，能组建大规模准分布式传感网络等特点，近年来已成为结构健康检测领域中的研究热点。本文介绍光纤光栅传感器( FBG)的特点和工作原理，综述国内外光纤光栅传感器在舰船结构健康监测领域的研究现状，探讨基于光纤光栅传感器的舰船结构健康监测系统的组成和主要研究内容。
