Paper Abstract

By illuminating a ground glass with a laser beam, a spatial field of speckles is created. These speckles are used as surface strain or displacement gauging elements of structures under static and vibrational deformation by coating the structural surface with photosensitive material. Equations used in obtaining the strain and displacement are shown.
