Abstract
A magnetooptic device to be used in industrial applications to investigate articles for flaws or defects. The magnetooptic device is capable of revealing defects in articles of nonmagnetic and magnetic conducting material. These results are achieved by designing a magnetooptic device having a magnetooptic transformer element on its bottom surface and incorporating a front electrical contact and a rear electrical contact on the bottom surface of the MO device. The respective electrical contacts are connected by wire conductors to the respective positive and negative terminals of a source of electrical current. The defect pattern of an article can be either visually viewed or the defect pattern can be recorded on a tape or magnetic rubber sheet placed between the bottom surface of the MO device and the top surface of the article being analyzed.
