Abstract

Double beam illumination is used to obtain contourline maps for the in-plane and out-of-plane deformation of reinforced concrete test specimen. Generally large rigid body movements hinder interpretation and have to be eliminated. The rigid body rotations of the test specimen are measured by means of a Michelson interferometer. The unwanted effects are eliminated by rotations around three axes of the holographic plate.
