  Abstract: This project is to observe the structural change of a rigid body using holographic non-destructive testing. Through the application of a specific voltage to a Peltier heating and cooling device, it is possible to produce a controlled temperature change on the surface of the object. Using the technique of double-exposure, a hologram can be generated that shows an interference pattern between the shape of the original object at rest and its shape after some sort of physical deformation. The goal is to view the way that heat propagates through a three-dimensional object using this technique, and the object's physical deformation over time with respect to controlled temperature change.
