1 March 1994 Speckle interferometry in material testing and dimensioning of structures
Author Affiliations +
A new 3D-Electronic-Speckle-Pattern-Interferometer, which was developed in the Institute for Experimental Mechanics of the Technical University of Braunschweig will be described. It is suitable for the whole field measurement of deformations of materials of elastic and non- elastic behavior. It is applicable in material testing, quality control and in dimensioning of structures. Because of its compact arrangement it can be attached to a testing machine or other loading constructions outside of an optical laboratory. The deformation components are determined nearly simultaneously for all three directions of a cartesian reference coordinate system. The presented arrangement gives a simple possibility to compare finite element calculations.
