Abstrakt

With contemporary easiness of access to advanced printing technologies and rapid prototyping
machinery, genuine marking becomes a great challenge for manufacturers who want to protect their
products from counterfeiting. This issue can be addressed by usage of unique marking techniques,
based on stochastic generation of marking templates. Difficulty of manual manipulation of
nanofibres, together with simplicity of their optical examination, makes them preferred candidates for
such applications. Fibres obtained by molecular beam epitaxy of parahexaphenylene (p6P), form a
unique pattern, which can be imaged under UV illumination by a CCD camera equipped with 5x
objective. With use of Radon transform, off-axis angles and coordinates of fibre’s terminations can be
extracted, and used as a set of data uniquely describing a given sample. Comparison of this set, with
database entry allows an easy and quick determination of product authenticity.
