Terahertz imaging benefits from the high power levels available with all-electronic sources. TOPTICA has signed an international distribution agreement with Frankfurt-based terahertz imaging specialist SynView GmbH. SynView, a spin-off from the University of Frankfurt/Main, is a technology leader in the field of all-electronic millimeter-wave imaging.
The SynViewScan systems use high-power electronic emitters at 100 GHz (SynViewScan 100) or 300 GHz (SynViewScan 300), and combine an xy scanning stage with a frequency modulation technique to acquire 3D terahertz data. The depth and thickness resolution is better than 20 µm for any single interface within a +/- 1 mm window, the spatial resolution is approx. 1 mm at 300 GHz. Using a heterodyne detection scheme, a dynamic range greater than 50 dB is attained. A full 3D image can thus be generated within only a few minutes.
The SynViewScan is the system of choice for non-destructive testing applications. It lends itself to the analysis of hidden structures in compound materials, and identification of manufacturing defects in production lines of semiconductors or ceramics. 3D imaging also enables a precise characterization of surface structures and coatings, even if the object under test is covered.
