埋入式光纤传感原理及实验研究——航天Smart结构

Sensing Principle and Experimental Study of Embeded Optical Fiber in Space Smart Structure

对Ｓｍａｒｔ材料／结构中的光纤传感原理进行了探讨，并进行了实验研究。首先介绍了Ｓｍａｒｔ结构中常见的埋入式光纤传感器的特点及其工作原理，然后提出了应用多模光纤在编织复合材料Ｓｍａｒｔ结构中进行应变场测量的方案，建立了实验装置，给出了实验结果并进行了讨论。

In this paper, sensing principle and experimental study of embeded optical fiber in smart structure are presented. Characteristics and principle of optical fiber sensors embedded in typical smart structures are described, and then a strain measuring method by using multi mode optical fiber in composite material structures is developed. A set of experimental system is set up, and some beneficial results are obtained and analyzed.
