摘要
设计了一种分布式FBG波长解调系统,采用可调谐光纤F-P滤波法对FBG的波长传感信息进行解调,使用高速采样卡对信号进行采集,分析。给出了阶段性试验的结果,并提出了改进系统分辨力的方法。
A distributed fiber-optic Bragg grating wavelength demodulation system is proposed.A fiber Fabry-Perot tunable filter is used to demodulate the wavelength of the FBGs,and a high-velocity digital sampling card is applied to collect and analyze the signals.Experimental results are given and methods of improving the resolution of the system are discussed.
