Application of laser method for determination of vector components of relative displacements and analysis of cyclic deformations

摘要

Abstract: The speckle twinkles and 3D displacements caused by 3Ddisplacement of 3D diffuser were investigatedtheoretically. Relative displacement of two specklepatterns generated by relative displacement of twodiffusers were examined. Non- contact technique fordetermining the vector components of relativedisplacements was worked out on the basis of obtainedresults. The technique was applied for experimentaldetermining of the relative displacements of the partsof rotating disk and for founding of the deformationsof cylinder periodically loaded. !10
