Abstract

In this paper, the new vector analysis for the three dimensional deformation measurement method with same sensitivity in three directions is proposed in order to analyze the deformation in an arbitrary direction on a measured object. The new analysis method is investigated by the results of experiments. The analysis is also employed in the three dimensional deformation measurement concerning a buckling phenomenon. In this measurement process, the usefulness of new vector analysis based on three dimensional speckle interferometry with the same sensitivity concerning each direction is discussed. As the results, the in-plane and out-of-plane deformations in the buckling phenomenon can be detected.
