In the first place , start with theoretic model of distributed fbg strain - sensing network , sensing principle of fiber bragg grating is analyzed and sensing model created . on the basis of analyzing advantages and disadvantages of several familiar multiplexing and demodulation techniques , a mixture multiplexing method that combines optical frequency domain reflectometry ( ofdr ) and wavelength division multiplexing ( wdm ) is proposed to address fbg sensing array . at the same time , tunable narrow - band light source , which is composed of wide - band light source and tunable optical filter , is adopted to demodulate multiplex signals
首先，论文从分布式光纤光栅应变传感网络的理论模型入手，分析了光纤布拉格光栅的传感机理，建立光纤光栅应变传感模型；在分析比较了常见几种复用技术和信号解调技术的优缺点基础上，提出应用光频域反射复用技术和波分复用技术相结合的混合复用方法来解决光纤光栅应变传感网络的寻址问题，采用由宽带光源和可调谐光滤波器组成的可调谐窄带光源来解调复用信号，通过理论分析和实验研究证实了系统方案的可行性。
