Abstract :
A way is presented for testing the surface crack with eddy current and the reconstruction of crack based on virtual instrument (VI ) . The reconstruction is a nondestructive technique enabled efficient crack testing based on much richer and comprehensive. Results of a relationship between surface crack and eddy current signals have been acquired by Maxwell´s equations, electromagnetic field theory and experiments. Then the surface crack image is reconstructed by VI.
