Abstract

A new wavelength detection technology about fiber Bragg grating(FBG) is reported, which is combined with the wavelet analysis. It can be used in wavelength multiplexing techniques, which can increased the degree of automatic calculation and the objectivity. By using this method, the spectrum of light wave is obtained better, thus, the influence of the side lobe voltage is solved by this method in wave processing, also the calculation speed is improved. The results of the experiments show that reflective signature is reconstructed preferable, and in addition, the influence on of the real peak detection which is caused by the side lobe voltage is wiped off.
基于小波分析的光纤光栅峰值波长检测技术
提出了一种结合小波分析的光纤布拉格光栅波长检测新技术。该方法可用于波长复用技术,提高了计算的自动化程度和客观性。利用该方法可以较好地获得光波的光谱,从而解决了波处理中旁瓣电压的影响,提高了计算速度。实验结果表明,该方法能较好地重建反射信号,消除了旁瓣电压对实峰检测的影响。
