摘　　要：分析了光纤光栅传感的优势及其系统组成,它采用波长调制,与光强调制和干涉调制相比,检测结果更加精确。同时利用波分复用等技术,串联多个布喇格光栅进行准分布式监测,对智能化建筑的实现很有帮助,并具体应用到一种力学模型—悬臂梁。This paper analyzes the superiority of fiber grating sensing and its system composition. It a-dopts wavelength modulation. Compared with the light-intensity modulation and the interference modulation, the test result is more precise. By simultaneously using such technologies as wavelength division multiplying to connect many Bragg diffraction gratings for distributional monitoring, it helps to intellectualize construction. A specific mechanical model, cantilever beam, is applied.
