摘要
研究了Morlet小波在光纤Fabry-Perot(F-P)低相干干涉条纹包络提取方面的应用,给出了Morlet小波尺度的计算公式。对不同信噪比(SNR)下低相干干涉峰值的提取作了仿真计算,并利用实测干涉图作了小波提取实验,验证了Morlet小波处理方法的有效性。实验结果显示,采用Morlet小波处理的低相干干涉解调方法的测量线性度好,线性相关系数为0.999 9。
The application of Morlet wavelet on profile retrieve of low coherence interferogram of optical fiber Fabry-Perot interferometer is studied and the formula for calculating the scale is provided.A series of simulations of profile retrieve under different signal noise ratios and the profile retrieve with experiment data are carried out.The results show the effectivity of Morlet wavelet.The loading experiment of optical fiber Fabry-Perot interferometer is performed,and the results processed with Morlet wavelet show that the measurement has good linearity with a correlation coefficient of 0.999 9.
