Abstract
THz spectroscopy exploits the farthest region of the infrared, at very long wavelengths. In this interesting
spectral range we observe fingerprint spectra of explosives and other solid chemicals, we observe the interplay
between molecules in the liquid phase, and we observe the motion of electrons in semiconductors. Bordering the
microwave and optical regime, the THz region has traditionally been difficult to access. Recent technological
developments have changed this, and today portable, high-performance spectroscopy tools for investigation of
the THz range is available.
In this presentation I will briefly outline the technological challenge for THz spectroscopy, give selected
examples of spectroscopic applications, and demonstrate portable instrumentation for THz spectroscopy and
imaging.
