Fiber Bragg Grating Peak Wavelength Detection Technique Based on Wavelet Analysis

摘要：

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 aniomatic calculationand the objectivity.By using this method,the spectrum of light wave is obtained better,thus,the influence of the sidelobe voltage is solved by this method in wave processing,also the calculation speed is improvedThe 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 sidelobe voltage is wiped off.
