Abstrakt v dalším jazyce:	The paper proposes a novel approach for enhancing eddy-current non-destructive evaluation. A detected crack is inspected using several probes that provide different distributions of eddy-currents. Thus, more information about the crack is obtained. The crack signals gained using the probes are superposed and unique features are extracted from the mixed signals. Numerical investigations as well as experimental verification reveal that the features provide clear indication about the depth of the detected crack. In addition, they enable one to evaluate the depth of a defect that is much deeper than the standard depth of penetration.
