ABSTRACT:
A measuring apparatus includes a heating unit for applying heat to a first point within a workpiece or on a surface of a workpiece and propagating the heat to a second point within the workpiece or on the surface of the workpiece. The measuring apparatus further includes a measuring unit for measuring a displacement of the surface of the workpiece at the second point to which the heat has been propagated, and an analyzing unit for analyzing a structure of the workpiece based on the displacement measured by the measuring unit in consideration of a distance between the first point and the second point.
