Paper Abstract

By combination with digital image analysis already known optical methods can get totally new field of application. With holographic and speckle-interferometry for deformation- and vibration analysis fringe images are evaluated which represent deformations or vibration amplitudes very exactly. With projection- or moire techniques micro- and macro-structures of the surface, as f. ex. 3-dimensional shape can be analyzed very exactly. Appropriate evaluation makes a partial frequency analysis of vibration forms induced by operation possible. The applications are described with concrete examples from car construction, in some cases with harder conditions as rotating components.
