Visual detection of subsurface defects using enhanced magneto-optic imaging system

摘要：

　　An enhanced magneto-optic (MO) imaging system is presented to detect the invisible and buried subsurface flaws in metallic specimens.The choice of the MO thin films,the design of the magnetic excitation device and the development of the image processing approaches are presented in this paper and the quality improvement in MO imaging has been demonstrated due to the proposed methods.Experimental results have been provided and verify the reliability and accuracy of the enhanced MO imaging system.
