Determination of Gabor wavelet shaping factor for accurate phase retrieval with wavelet-transform

摘要

We examined the range of shape factor of the Gabor wavelet in the analysis of spectral phase retrieval with an inter-ferogram. We demonstrated that for the pulses with moderate high order phase the accuracy of the retrieved phase is insensitive to the shaping factor in the range of 1 ～ 20. Both simulated ideal Gaussian spectrum and actual non-Gaussian spectrum are applied in the analysis.
