Terahertz bench for comprehensive characterization and non-destructive testing of laminated materials

Over the past three decades, science community has seen development and emergence of terahertz technologies. This frequency range which is halfway between optical and radio wavelength is very interesting since most of materials show transparency in this band. Furthermore, emission et detection techniques of such rays allow to get amplitude and phase of the signal. In this paper we propose to exploit these properties with a terahertz bench that can acquire signals reflected and transmitted from a laminated sample with different incident angles.
