Application of areal topography parameters

Topography parameters quantitatively describe the state of the surface. Topography parameters can be divided into two basic groups: line (2D) and areal (3D) topography parameters. Unlike the line topography parameters obtained by measuring the sample surface by passing the probe along one line, the areal topography parameters are obtained by measuring the surface area. In order to unambiguously describe the surface, there are a large number of areal topography parameters that describe the state of the measured area. These parameters can be classified into several groups: amplitude, spatial, hybrid, functional and miscellaneous. The paper presents and defines the surface areal topography parameters, as well as the application of the selected parameters.
