| Zusammenfassung | The last fifteen years of progress in measurement and room-temperature instrumentation for the 100 GHz – 10 THz spectral region is surveyed. This includes the development of SI traceability through a national metrology institute (NMI) for free space power measurement over the full THz range, and for the extension of NMI-based waveguide-coupled traceability chains up to 330 GHz. Potentially traceable power measurement with Rydberg-atom sensors is described, along with statistical methods for low-level power measurement and uncertainty estimation when using e.g. zero-bias diodes or pyroelectric sensors that are commercially available and sensitive but not necessarily traceable. Blackbody targets are also discussed, which are essential components for THz remote sensing instruments, and for validation of THz receiver performance. |
