The paper presents an eddy current tomography setup with high spatial resolution and high accuracy of measurements of signal on detection coil. In proposed solution both amplitude as well as phase shift are measured, which gives the possibility of calculation of spatial distribution of both permeability and resistivity of tested element. As a result, presented setup creates possibility of effective detection of discontinuities in cylindrical elements, which opens new possibilities for industrial applications of eddy current tomography.
