This paper discusses the development of an ultra-broadband terahertz (THz) spectrometer with bandwidth > 20 THz, which significantly extends the capability of the THz pulsed imaging technique. This study also shows how time-partitioned Fourier transforms of the measured THz time-domain signal after transmission through a sample allows the progressive observation of absorption and subsequent emission of THz radiation at the frequency of the vibrational mode.
