The THz time-domain spectroscopy (THz-TDS) knew a rapid development due mainly because of the appearance of commercial femtosecond pulse laser in the late 1990s. First focused on the development of the tool and for materials characterization in the typical bandwidth from 100 GHz to a several THz, the research then extended, in the 2000s, to the characterization of devices then cruelly missing in this frequency range. Since then, the number of laboratories interested in this technique, and more generally in this frequency domain, has increased exponentially, concerning ever more numerous scientific fields ranging from physics, chemistry and biology to other more applicable for non-destructive testing, the detection of "sensitive substances"... In this context, I will present a review of my research since the construction of the first THz-TDS setup and the measurement of the first signal in 1995, up to my more recent works, some of them being more applicative, like for example to propose a solution for identification of products in the THz range and based on THID tags.
