Application of VFW techniques for image capture in magneto-optical / eddy current imaging system

According to eddy current effect and Faraday magnetic-optic effect,a new Magnetic optic / Eddy current imaging system is designed in this paper to test the imperceptible flaws in subsurface of mental product nondestructively and realize visualization testing.An image processing system is designed by VC and the image of the imperceptible flaws is captured by VFW Technique.The experimental results discussed in this paper prove that the system is feasible and appropriate.
