Abstract

Abstract An enhanced magneto-optic (MO) imaging system is presented in this paper to detect hidden and buried subsurface flaws in metallic specimens. The characters of the MO imaging system are mainly given by the parameters of the MO thin films, the magnetic excitation device and image-processing algorithms. In this paper, the choice of the MO thin films, the design of the magnetic excitation device and the development of the image processing approaches are introduced in detail. Experimental tests have been done and the method presented is evaluated by the experimental results.
