摘　　要：对光纤布喇格光栅径向受力特性进行了理论与实验研究,给出了光纤布喇格光栅的径向受力灵敏度,并利用可调F-P标准具设计了一套解调光纤布喇格光栅反射峰劈裂值的实验系统.此系统消除了外界环境对F-P标准具初始腔长的干扰所引起的误差,系统的准确度达到了0.02nm.The characterization of the response of fiber Bragg grating subjected to a diametric load is studied and the diametric load sensitivity of fiber Bragg grating is demonstrated. A demodulation system for Bragg wavelength splitting changes using a tunable Fabry-Perot etalon is also established, which can eliminate the deviations caused by the environmental influence on the initial length of the cavity of the Fabry-Perot etalon, and hence a resolution of 0.02 nm can be obtained
