st part of innovation but, I would like to add in full agreement with him, the most essential. Without successful research innovation is not possible at all; but neither research and invention nor any other step in an innovation procedure can be left out. Our philosophy is to keep researchers involved until t978-3-662-02365-5978-3-662-02363-1

Hardware-Equipment for Automatic Ultrasonic Inspection by the ALOK-Techniqueudinal as well as shear waves at frequencies from 1 to 4 MHz the described system has the following important and newly developed features :.The recorded data is analysed by the ALOK procedure reconstructing the size and location of defects.

Pulse-Synthesis and Pulse-Adaptation in Ultrasonic Imaging for NDTin acoustic imaging systems. Optimum short pulses can be created in the frequency domain as well as in the time domain by matching synthesized input signals to the imaging system. Furthermore, adaptation of synthetic signals to special reflectors is possible.

An Ultrasonic Phased Array System for Defect Classification and Reconstructiony sector and compound scanning are described. The reconstruction methods are characterized by high redundancy, high detectability and rapidity. Recording only the intensity maxima of the image spots, the reconstruction is, to a large extent, independent of beam width and system sensitivity.
