Thermal expansion tensor measurement by holographic interferometry.
The displacement on a plane, originated by a temperature increase of three perpendicular flat plates, is measured by means of a double exposure hologram. These displacements allow us to calculate the thermal expansion tensor of an anisotropic material.
