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.
