| Sumario: | This paper presents a research developed in the Applied Optics laboratory of the Universidad Nacional de Colombia, Bogotá, and it is based around an application of the double exposure digital holographic interferometry (DHI) for measurements of micro deformations. We made holographic digital recording in off-axis confi guration using a set-up type MachZehnder interferometer of an iron-nickel plate was put under a mechanical effort, with the pur-pose of measure its deformation by the double exposure IHD technique. From the numerical reconstruction and the superposition of the holograms of the object, before and after its deformation, we obtained the phase difference, which is proportional to the deformation produced to the object. |
