Aa. Chugunov et al., GRAPHICAL INTERPRETATION OF ELECTROMAGNETIC TESTS ON FUEL-RODS FOLLOWED BY DATA-ANALYSIS, Russian journal of nondestructive testing, 31(7), 1995, pp. 551-556
A system has been developed for the graphical processing and interpret
ation of eddy-current sensor signals on the basis of an IBM personal c
omputer. The signals are represented as three-dimensional frequency sp
ectra of various types. That representation raises the signal-noise ra
tio substantially in eddy-current flaw detection on components and fue
l rods in power reactors. Artificial defects are represented by means
of a three-dimensional graph.
