Abstract: This paper is focused on the nondestructive inspection of concrete rebars by using eddy current testing. Many practical low frequency systems are capable of locating and estimating the size of the cross-section of the rebars via calibration charts. Here we develop a quantitative non-iterative imaging method based on a numerical model of the probe-specimen interaction.

Keywords: Non-iterative inductive imaging, NDE, eddy currents, reinforced concrete inspection
