中文摘要：

收集了纤维布拉格栅栏(FBG ) 的光谱，检测光力量的损失关于一种 Fabry-Perot (F-P ) 类型的 3-dB 带宽被讨论悦耳的光过滤器(TOF ) 分别地。并且 TOF 的优化参数因而被获得。在 TOF 和它的开车电压的传播波长之间的关系是非线性的，这被表明。补偿 TOF 的非线性的一个新方法被建议。TOF 的传播波长的线性扫通过用插值算法修改开车电压被完成。平均误差和传播波长的最大的错误严厉地被减少在下面，这被观察线性合适。察觉到的动态种类被引用 FBG 和动人的平均算法的使用在这个系统认识到。

英文摘要：

The collected spectrum of the fiber Bragg grating （FBG） and the loss of the detected optical power are discussed with respect to the 3-dB bandwidth of a Fabry-Perot （F-P） type tunable optical filter （TOF）, respectively. And the optimized parameters of the TOF are obtained consequently. It is demonstrated that the relationship between the transmission wave- length of the TOF and its drive voltage is nonlinear. A new method to compensate the nonlinearity of the TOF is proposed. The linear sweeping of the transmission wavelength of the TOF is achieved through modifying the drive voltage using interpolation algorithm. It is observed that the average error and the maximum error of the transmission wavelength are reduced sharply under linear fit. The dynamic strain sensing is realized by use of a reference FBG and moving averaging algorithm in this system.
