All known tests relate to the inspection or test procedures in which the products are destroyed. The previous labeling is obvious and not forgery-proof. Therefore, the number of unrecognized, sophisticated counterfeits is estimated very high. The associated economic damage to industry and endangering the health of the population is a serious problem.

  • Terahertz radiation is electromagnetic radiation in the frequency range between 0.1 and 10 THz. Many compounds, materials or composite materials exhibit characteristic signatures in their absorption spectra in this spectral range. THz radiation is characterized by a high permeability. A preferred THz method is Time Domain Spectroscopy (THZ-TDS). Broadband electromagnetic THz radiation is generated by ultrashort femtosecond laser implants (fs). The laser radiation is divided into pumping and scanning beam. The pump beam is focused on a THz emitter. Such generated THz radiation is specifically broken and absorbed after impact with a sample, here original product or copycat product. The specific refraction and absorption also occurs at the intrinsic label and / or the additional label provided.
