Abstract
New methods for determining geometrical parameters of cylindrical bodies (the outside diameter and wall thickness) based on the theory of elastic acoustic waveguides have been suggested. These methods enable one to measure these parameters over broad ranges even if there is no free access to the surface of a tested object.
