Abstract

In a method for detecting the deformation of objects (1), a sequence of pictures of the object (1) is taken with a measurement method during the deformation of the object (1). From the pictures, phase images are determined. To improve such method, there is formed the difference between the current phase image or the respective current phase image and the phase image of an initial state. This difference or these differences is/are evaluated and/or displayed on a visual display unit and/or stored.
