Abstract
A system for the processing of signals collected by an eddy current absolute point transducer moving along an inner surface of a conductive material tube and supplying a representative signal concerning the state of the inner surface. The system incorporates a stage for scanning the surface in accordance with a given order or sequence of elementary measurement zones and recording the sampled values of the signal supplied by the transducer for each of the elementary zones, which makes it possible to obtain a three-dimensional image representative of the surface. The system also constructs a background noise surface on the complete image, subtracts the background noise surface from the image and detects a defect or fault on the surface. Such an invention may find particular application to the inspection of steam generator tubes.
