Abstract
The "Synthetic Aperture Focusing Technique" is applied to analyze defects by a remote controlled ultrasonic equipment. Examples are shown to demonstrate the advantages over conventional approaches. The newest implementations include the data transfer into 3D-CAD-drawings from the components which allows a correct location of the image with respect to cladding or welding and are based upon CAD-models to reconstruct even data obtained on components with arbitrary surface shapes. The program runs under Windows NT or Windows 95 on Personal Computer.
