Paper Abstract

A novel method for identifying hidden defects in new products or in worn but valuable recyclable components is described. This method is based on the fact that the vibration behavior of mechanical objects is influenced by defects or material fatigue. For detecting hidden defects the vibration frame of the objects is scanned with a laser- scanning vibrometer. The scanned information is analyzed in an image processing unit. At last a quality evaluation is made.
