理论研究了啁啾脉冲频域干涉仪的时域相移重建技术，对于接近实际的频谱干涉条纹，分别采用傅里叶变换和小波变换的方法完成了时域相位扰动信号的重建。傅里叶变换方法产生的重建误差受到滤波参数的影响，相对而言，小波变换方式解谱过程中，不需要进行特意的滤波操作，从而避免了重建结果存在误差不确定性的问题。

Reconstruction of phase perturbation in chirped pulse spectral interferometry is theoretically studied. As for spectral interferogram approximating to the fact, the wavelet transform and Fourier transform are used to reconstruct phase perturbation in time domain. The reconstruction errors are affected by the parameters of filter employing Fourier transform, however, when the wavelet transform is used, it is not necessary to carry on filtering specially, therefore uncertainties of reconstruction errors are avoided.
