How does the terahertz measurement work?

The TERASCOPE® uses terahertz waves in a broad frequency range from up to 6 THz*. With a wavelength of less than 1 mm the terahertz waves are shorter than microwaves but longer than visible light. The special feature of THz waves is that they can penetrate numerous organic and dielectric layers. Each individual layer within a multilayer system can be detected separately.

The terahertz waves are generated in the measuring head by an optoelectronic unit with a laser. This emits ultrashort terahertz pulses that is sent to the sample. These pulses penetrate the different layers. At the transitions between the layers, the waves are partially reflected. These echo pulses arrive at the detector with characteristic time differences. Since each layer and each material has specific absorption spectra, individual layers and their layer thickness can be precisely determined from the signal characteristics, and other parameters such as homogeneity and porosity can be inferred.
