摘要
光纤光栅传感系统的测量信息以波长编码的形式被解调系统接收,通过测量波长的移动得到传感信号的变化,波长编码信号的解调是光纤光栅传感系统工业化的关键技术之一。总结了目前出现的多种光纤光栅传感解调系统的工作原理,分析了各自的特点,重点分析了滤波解调法,并在此基础上展望了光纤光栅传感系统解调技术的研究方向。
Metrical information of fiber grating sensing system is received by demodulation system in the form of wavelength encoded.Variation of FBG signal can be measured according to the measurement of wavelength shift.Therefore,the signal demodulation on the wavelength coded is a key technology for the industrialization of the optic fiber grating sensing system.In this paper,the principles and characteristics of various FBG sensing demodulation systems are summarized.The filtering and demodulation methods are emphatically analyzed,and the research direction of demodulation technology of FBG sensing system is prospected.
