Nowadays many techniques exist to determine the different physical properties of a material. The elastomers, or called rubbers too, are materials that can be deformed by the external loads application, their use and application depends of the material physical properties. A physical property that should be kept on mind to study the diverse associated applications to a material is the Young’s module. In this work, we use the electronic speckle patterns interferometry (ESPI) technique to measure the natural rubber latex Young’s module. A dual illumination interferometer of equal angles to both surface normal sides was implemented, the shifting phase technique and a four frames algorithm were used to find the phase maps. Besides, to apply the external loads to the rubber latex sample an electromechanical traction system was build. We verify that ESPI technique can be used like optical extensometer to determinate mechanical properties of materials and components in the industry. The Young’s module is compared with a reference Young's module.
