Description:

The term optical profilometry is used in relation to group of methods used in a rapid, non-destructive, and non-contact assessment of surface topography. Those methods playing a signifi-cant role in the area of a modern advanced laboratory and industrial 3D measurements. With the development of profilometric methods, a large progress in the construction of optical profilometric instruments and measuring sensors used in them, including confocal sensors based on the chromatic light aberration phenomenon (CLA) has been observed since several years. In the paper shows that the Talysurf CLI 2000 multisensory optical profilometer equipped with a CLA sensor can be used in high-accuracy 3D measurements of the uncirculated and circulated coins. The assessment of such type objects characterized by a high variability of altitude can be extremely helpful in analyzing the actual metrological properties of measuring equipment used in their measurements.
