摘　　要：提出了一种使用匹配光纤光栅闭环跟踪测量传感光纤光栅布拉格波长移位的方法,该 方法适用于单点检测,并且具有动态响应好,测量动态范围大,受环境影响小,测量精确度高的特点。A novel method is presented for detecting the wavelength shift reflected by the sensing fiber Bragg grating. The system employs a matching grating, having the same parameters as the sensing fiber Bragg grating, to track the sensing grating through a closed-loop system. It has the advantages of fine dynamic response, wide dynamic range, high sensitivity and immune to environment.
