Abstract
In the paper, the potentials of multi-frequency eddy current measurements for non-destructive testing of geometric characteristics of metallic materials are considered. To enhance such potentials, experimental hodographs for copper plate testing samples of various thicknesses with applied dielectric layer are processed by projection methods of multidimensional data analysis. Application of principal component analysis ensures a sufficiently reliable separation of competing factors that affect the controlled parameter-the thicknesses of a metal plate and a dielectric layer. Principal components regression allows for the development of mathematical models for high...
