Paper Abstract

This contribution focuses on applying the unique optoelectronic THz beam system we have developed to THz time-domain spectroscopy (TDS). The work developing the system is first reviewed. The emerging technique of THz-TDS is introduced, and some past applications are described. We then present a theoretical and experimental comparison between THz-TDS and the well-established Fourier transform spectroscopy (FTS). The extraordinary dynamic range of THz-TDS allows the study of exceptionally optically dense materials; specific past examples and new opportunities are discussed. The topic of difficult samples is explored for samples, such as flames, posing exceptional problems for FTS, but which can be relatively easily measured with THz-TDS.
