N2 - This paper presents an experimental investigation of a rotating eddy current (REC) system for subsurface defect detection in CFRP composites. The proposed solution employs a compact four-coil excitation probe and a controlled excitation strategy to rotate the induced eddy currents while maintaining a constant current amplitude. Experimental measurements were performed on CFRP laminates containing circular subsurface defects with different diameters and depths. The results demonstrate that the proposed REC system is capable of detecting and distinguishing defects as a function of their geometrical characteristics. The proposed REC system has improved robustness against material anisotropy, confirming the potential of the proposed approach for reliable CFRP inspection.
