Paper Abstract

In the present work an interferometric approach based on the implementation of a digital holography setup is discussed. It is used to determine interferograms of materials under small deformations. In order to do this, a fixed-free cantilever beam subjected to a concentrated force applied at the free end is taken into account. The experimental procedure to estimate displacements is carried out using digital Fourier transform holography (DFTH) technique. This is obtained making a very simple modification in the classical setup architecture of the DFTH setup. It is also demonstrated the easy and practical viability of the setup in an interferometric application for mechanical parameters determination.
