Description

A considerable amount of attention has been focused in recent years towards the development of probability of detection (POD) models for a variety of nondestructive evaluation (NDE) methods. Interest in these models is motivated by a desire to quantify the variability introduced in the measurements during the process of testing. As an example, sources of noise in eddy current methods of NDE include those caused by variations in liftoff, material properties such as conductivity and permeability, probe canting angle, scan format, surface roughness and measurement noise. Fig. 1 pictorially depicts some of the factors that contribute to variations in the measured signal.
