Brief description of the ibg innovation Simultaneous Harmonic Analysis in eddy current testing. The iSHA technology (ibg’s Simultaneous Harmonic Analysis) enables a simultaneous calculation of the vectors of the fundamental wave and two harmonics of up to eight frequencies without extension of test time. It additionally uses high frequencies and their harmonics for a better solution of even the smallest structure differences. Thus iSHA greatly enlarges the possibilities of the well-known Preventive Multi-Frequency Technology (PMFT) for industrial applications. Text and poster were prepared for a short lecture at the DGZfP Annual Meeting in 2013.
