Abstract
An apparatus and method for determining the shape specific contraction and expansion of cylindrical or otherwise geometrically regular-shaped products as a function of time and temperature through high precision, continuous, nondestructive dimensional analysis of a cross-section of the object as the object is heated and/or cooled. The apparatus includes multiple penetrating radiation sources and detectors. In performing the analysis on an object as its temperature changes over a certain temperature range, the apparatus generates curves or formulas representing the changes in a dimension of the object as a function of temperature and/or time.
