METHOD AND APPARATUS FOR FLUORESCENT MAGNETIC PARTICLE FLAW DETECTION

摘要

PROBLEM TO BE SOLVED: To provide a method and an apparatus, for a fluorescent magnetic particle flaw detection, in which the height of the apparatus can be kept within a limitation range while a desired flaw-detection visual field is ensured. SOLUTION: A flaw which exists on the surface W1 of a material W to be inspected is detected by fluorescent magnetic particles. The image on the surface W1 of the material W to be inspected by a static-image imaging means E which is used to image the static image of the material W to be inspected is refracted by a reflecting mirror 13.
