Abstract
This paper presents results pertaining to image data obtained from a p lanar meander-mesh coupled coil type ECT probe. The image data makes i t possible to detect not only the existence of a defect but also to ex tract detailed information regarding the nature of the defect, such as its position, shape, length, and direction, In order to recognize a d efect distinctly, we have fabricated the high sensitive planar coil wh ich can be used to image a 2-D representation of the ECT signal, The r elationships between the image pattern and defect shape are discussed.
