Terahertz time-frequency analysis with Gabor wavelet-transform

  • 1. 

Abstract: We applied different shaping factors of Gabor wavelet for the analysis of terahertz time-domain spectroscopy with wavelet_transform. Gabor wavelet analysis allows a convenient switching between time domain and frequency domain by varying shaping factors. The comparison of absorption spectral lines obtained between with wavelet-transform and with other methods demonstrated that wavelet-transform is a reliable technique for the analysis of the absorption properties and the extraction of the characteristic spectral lines in terahertz range.
