Abstract

The increasing demand for better characterisation ofmaterials and components in many cases requires ftill field information for the analysis of the mechanical behaviour. 3D Speckle Interferometry offers the possibility to obtain full field and non contact deformation and strain analysis of materials and components. The principle and theory of this technique have been well known since several years. Novel designs now offer the opportunity of easy application in the field of material and component testing.
