An important area of application of Shearography is non-destructive testing (NDT). Defects become visible on the basis of the measured inhomogeneous deformation- respectively strain-distributions. Beyond the localisation, the defects or the mechanic structure of the object can be further characterised dependent of the spatial distribution. The identification of material parameters of damaged areas is possible as well in combination with fem-models.
