| Abstract | 将小波变换引入THz波时域光谱技术.将水蒸气的THz波时域信号通过小波变换转化为二维的时间-频率平面,得到了和文献报道数据相一致的水蒸气的吸收谱线.同时发现了THz波频谱的时域分布特性,这将有利于进一步研究THz波与物质相互作用的内在机理. The application of the wavelet-transform to terahertz time-domain spectroscopy ( THz-TDS) is described. Using wavelet-transform to analyze the time-domain signals passing through water vapor measured by time-domain spectroscopy, we got the absorption spectra of water vapor in the frequency range from 0.5 to 2.5THz, which agree well with the results reported in the literature. Moreover, wavelet-transform in THz-TDS opens up a new way for the analysis of the time-domain properties of absorption spectra of water vapor. |
