A terahertz sensor operating in a frequency range between 500GHz and 2,500GHz will be shown by the Ferdinand-Braun-Institut (booth 4545). The sensor offers sensitivity of NEP 50pW/Hz0.5 along with a fast response time. It is suited for imaging systems used for quality control in industrial applications, and can also be integrated into medical equipment, for example for diabetes diagnostics and spectroscopy. The terahertz camera sensor is based on the institute’s in-house GaN-HEMT MMIC process.

On the same booth, the Fraunhofer Heinrich-Hertz-Institut will demonstrate its continuous-wave terahertz system, T-Sweeper. The system provides a measurement rate of up to 60 points per second, which makes the T-Sweeper a cost-efficient alternative to pulsed terahertz systems.
