Characterization of biological materials by means of optical methods of measurement

This study presents the different possibilities of measuring mechanical quantities on biological materials by means of optical methods. These methods allow to perform non-contact and non-disturbing evaluations. The goal is to determine the mechanical characteristics of human organs to be able to model them in order to carry out digital simulations closer to reality. We will set out a method which measures the relief, another one which measures a field of displacements and the last one strain tensors.
