Project of the Scientific Grant Agency VEGA 2/0126/13

Duration of the project: 01/2013 - 12/2015

Principal investigator: RNDr. Miroslav Hain, PhD.

The project aimed to the proposal of new methodologies of measurement and non-destructive testing, theoretical analysis and experimental verification of the measurement by X-ray microtomography and active infrared thermography. Priority was given to the solution of specific challenges resulting from the use of these methods in measurement and non-destructive testing of hidden subsurface defects, inhomogeneities in materials and visualisation of internal structures and microstructures of objects. It has been carried out a theoretical analysis of thermography and microtomography measurement systems, limits of these methods in terms of resolution and uncertainty of measurement was analyzed, and calibration methods were proposed. Specifically in the case of X-ray microtomography sources of the artifacts in the measurement process were identified and the uncertainty of measurement of internal structure and porosity of materials was analyzed.
