Abstract
Disclosed is a borescope-based inspection method for inspecting a condition of an externally invisible component of a device, in which method a change in the microstructure of the component material is determined based on a physical property and evaluated in relation to at least one reference physical value that accounts for aging of the component. Also disclosed is a system having a computing unit and at least one probe for performing such an inspection method for selecting, with the aid of or, in particular, by a computer, a non-destructive testing method for measuring the physical property and for actually measuring the physical property, for performing a comparison between a measured value and the reference value and for performing an evaluation of a tolerance between the measured value and the reference value.
