Abstract :
This paper discusses an imaging of eddy current testing (ECT) data for surface breaking evaluation. The ECT probe used in this paper consists of transmit-receive (TR) type sensors as array elements to obtain the information on flaw directions, as well as deep situation. Switching two-directional scan modes gives two-dimensional vector mapping as ECT images. The ECT signals of the TR type sensor also give the information on flaw directions from their variation displayed on the complex number plane. Operating a complex number component of the signals visualizes directions of surface breaking
