Fraunhofer Heinrich Hertz Institute HHI, Berlin, and TOPTICA Photonics AG, Graefelfing, present in the Control exhibition a terahertz platform of the latest generation that achieves a total bandwidth of 6.5 THz and a peak dynamic range of more than 95 dB in less than 20 s is presented. For in-line testing with sub-second measurement times, the usable bandwidth still remains well above 5 THz. This system is a result of an intensive collaboration between the two partners, with TOPTICA Photonics AG being a dedicated terahertz system provider, and the Fraunhofer Heinrich Hertz Institute HHI, which specializes in the development of high-performance terahertz sensors and systems. The terahertz platform can be combined with a fully automated layer thickness measurement system for non-contact inspection of paint and coatings (see Fig. 1). Multilayer coatings consisting of up to five layers with individual thicknesses between 5 µm – 80 µm can be resolved. Thickness values are automatically calculated from the measured pulse trace by using a transfer matrix algorithm. The accuracy of the thickness measurement is better than 0.5 µm and the reproducibility of consecutive measurements is higher than 1 %. Hence, this measurement system is an important step for bringing terahertz sensors into a wide range of industrial applications.
