Abstract

Attached-grating moire was used to measure the displacement field of a wall that was sheared with both constant and cyclic load and, in a subsequent experiment, was deformed by a perpendicular load. A moire grid of large size (2 X 3 m²) was realized on the object surface. With its aid, the shear component in plane and one component of the out-of-plane displacement field, respectively, were determined by a phase shift algorithm. The results are compared to photogrammetric 3D data that were taken simultaneously. The calibration is discussed. We sketch the influence of phase errors and propose an algorithm to correct for them.
