COMPUTED TOMOGRAPHY – A NEW METHOD IN THE FIELDS OF DIMENSIONAL METROLOGY AND MATERIAL INSPECTION

Computed tomography is a new method which uses X- rays to simultaneously obtain information of both external and internal characteristics of measuring object. The method itself has been known since 1970s, but still its application in dimensional measurements begins only two decades ago. It is a non-destructive and non-tactile method which makes it particularly suitable for material inspections. It is ideal for investigating inner structure of materials, as well as for detecting holes and imperfections inside material. What makes this method uncompetitive are lack of measurement traceability and high number of influential parameters, which make calibration and uncertainty determination problematic.
