智能结构系统中的光纤传感技术

Fiber-Optic Sensing Technology in Smart-Structure Systems

智能结构系统具有类似人体运动控制功能,埋置在工程结构或材料中便能获得顺应环境变化的自判断性、自适应性、自诊断性、自修复性等诸多性能.这一神奇的科学技术具有重大科学意义和广阔的应用前景.利用特性优良的光纤传感器可以构成一种特殊的光纤智能结构系统.本文较深入介绍适合智能结构系统的光纤多点式和分布式传感技术的原理、结构和实施方法.

The smart-structure systems offer motion control function somewhat similar to human body. When they are embeded in engineering structures or materials, some properties adjusting to environmental temperature, such as self-identif ication. self-adaptation. self-examination and self-renovation , can be obtained. Therefore, this kind of technology will open up wide application prospect. Using the fiber-optic sensors with excellent properties, an unique fiber-optic smart-structure may be constructed. This paper presents the principle, structure and practical method of multipoint and distribution fiber-optic sensing technology with smart-structure in detail.
