An application of electromagnetic nondestructive evaluation is presented in the paper: Laser scribed markers used as logistic codes on metallic components are reconstructed from the signal of an eddy current probe. The authors developed a computational model of the reading out process by which both the code specification and the probe can be optimized. The model is applied here for the optimization of marker density. The reconstruction of barcode using inverse filtering approach is also demonstrated.
