Paper Abstract

In order to exploit new possibilities of THz sensing and imaging, it is not only necessary to generate and detect THz radiation but also to measure the radiant power of the THz sources and the responsivity of the detecting systems traceable to the international system of units (SI). This has been missing in the THz range up to now. The Physikalisch- Technische Bundesanstalt (PTB) has focused on this challenging task by using two complementary optical approaches: source- and detector-based THz radiometry. Both methods have been successfully prototyped, and a pyroelectric THz detector with known aperture was used to verify the consistency of the two independent calibration methods.
