| 1. A method for detecting an internal physical attribute of a manufactured object using an energy measuring device, the method
comprising:
measuring energy reflected from within the manufactured object with the energy measuring device to obtain a measured complex
signal indicative of a structural defect within the manufactured object, the internal physical composition of the manufactured
object comprising non-homogeneous material;
comparing the measured signal to an expected result associated with the manufactured object;
determining the structural defect based on the step of comparing; and
displaying the determined structural defect.
