Functional Correlation

  • Christopher A. BrownEmail author
Reference work entry



Functional correlation in surface metrology refers to the relations between the surface and phenomena that influence or are influenced by the topography. Establishing functional correlations is one of the principal objectives of research in surface metrology.

Theory and Application

There are two kinds of functional correlations. These are called correlations of the first kind when they are between phenomena that created or modified the surface and the topography. They are called correlations of the second kind when they are between the topography and behavior, or performance, of the surface (Fig. 1).
