| Abstract | 将小波变换法引入光谱相位相干电场重建法的相位重建,从光谱干涉条纹的小波变换中直接读取条纹相位,消除了传统傅里叶方法滤波过程中产生的相位噪声.这种方法将有利于超宽带、单周期超短脉冲的产生,更适用于超短脉冲的评价. We introduce the wavelet transform for phase reconstruction of SPIDER in this paper. With the technique, we can directly read the phase from the wavelet transform of spectral interferogram, which essentially eliminates the phase noise resulting from improper temporal filters in the conventional Fourier method. The simulation and the practical example proved the validity and reliability of this technique. This technique will find more applications in generation and characterization of monocycle optical pulses. |
