摘要
论文以提高光纤光栅传感器信号解调系统的波长检测精度为研究主题。在改进质心寻峰算法的基础上,分析了几种基于可调谐F-P滤波器的光纤光栅传感器波长解调系统的算法,并使用LabVIEW语言对其进行了仿真对比研究,提高了波长解调的精密度。实验结果表明,论文提出的质心法寻峰,抛物线插值算法有效地提高了光纤光栅反射信号解调系统的波长解调精度,降低了复杂程度。
The method to improve the precision of the FBC- demodulation system is studied. Based on improving the centroid peak searching algorithm, analyzing and some critical algorithm in the FBG demodulation system, using LabVIEW program to simulate and con- trast, the precision of wavelength demodulation has improved. The results of the experiment show that using the fitting centriod peak search- ing algorithm and the parabolic interpolation can improve the precision of the wavelength demodulation system. It also can reduce the com- plexity of the system.
