Integral Thickness Measuring
Terentyev D.A.
Abstract
The method of integral thickness measuring has been
developed. It is realizable on the basis of standard AE systems
and AE sensors. On the object at a distance of several meters or
tens of meters apart two AE sensors are placed. They are used as
a transmitter and a receiver of the acoustic signals. On the
spectrogram of received signal the dispersion curves are
extracted. The arithmetic mean thickness, the thickness
dispersion, and the estimation of the minimum thickness can be
calculated.
