What is profilometry?
Profilometry is the measurement of relief. This analysis makes it possible to evaluate the roughness of a sample and can be carried out along an axis (2D) or along a surface (3D).
What techniques can be used?
The objective of the measurement is to establish an altitude profile of a sample. For this, there are two groups of techniques: so-called “contact” techniques and so-called “contactless” (optical) techniques. The technique chosen depends on the materials to be analyzed and the desired resolution.
What are generally the deliverables of a profilometry study?
The deliverables of a study are generally representative images of the analyzed surfaces, relief curves along chosen axes, and finally roughness parameters calculated from the reliefs.
