1. A method for non-destructive detection of signs of aging of a component having regularly recurring structures, comprising:
a) scanning the component in a region of the recurring structures in a plurality of scanning planes which extend parallel to one another, creating at least one scanning image set having a plurality of two-dimensional scanning images, wherein the scanning images show a multiplicity of inhomogeneities;
b) automatically identifying those inhomogeneities that form recurring patterns and those inhomogeneities that do not follow a recurring pattern, using a suitable algorithm; and
c) detecting signs of aging exclusively on the basis of those inhomogeneities identified in step b) that do not follow a recurring pattern;
wherein the regularly recurring structures are one or more winding layers wound around a winding bar.
