Abstract
We introduce a new technique for the joint time-frequency analysis of terahertz time-domain spectroscopy based on wavelet-transform technique. With this technique, the frequency components in the different parts of the pulse are clearly exhibited in different time locations. This technique avoids interference spectrum even when the echo terahertz pulse emerges. By varying the shape of the analysis wavelet, high time resolution and high frequency resolution are easily obtained.
