Abstract

The speckle twinkles and 3D displacements caused by 3D displacement of 3D diffuser were investigated theoretically. Relative displacement of two speckle patterns generated by relative displacement of two diffusers were examined. Non- contact technique for determining the vector components of relative displacements was worked out on the basis of obtained results. The technique was applied for experimental determining of the relative displacements of the parts of rotating disk and for founding of the deformations of cylinder periodically loaded.
