Abstract

In the beginning of this article we briefly outline the working principle of terahertz imaging. This relatively new technique is based on THz time-domain spectroscopy and has the potential to lead to the first portable far-IR imaging spectrometer. For such a spectrometer many applications can be foreseen in the fields of biology, medicine, chemistry and material science. Here we present two biological applications. First we show that THz-imaging is an ideal tool for dendrochronology as it allows us to obtain density profiles of wood specimen. Secondly, we monitor water take up in plants after plant water stress.
