  • Abstract
    A new giant magnetoresistance (GMR) based eddy current field measurement system which can inspect components at rates comparable to magneto-optic imaging (MOI) sensor systems has been designed and developed. The main advantage of this system over the MOI is its ability to retain complete quantitative information about the magnetic field. Other advantages of the system include high bandwidth and sensitivity.
