A tendency towards growing requirements for the inspection of austenitic piping can be observed in several countries. In Germany the revised KTA rule demands the UT inspection of austenitic and dissimilar metal welds in piping with diameters of 200 m

In this paper an eddy current imaging method for nondestructive testing purposes is presented which utilizes the concept of broadband holography. An eddy current coil which is used simultaneously as an antenna for eddy current generation and as a pro

Resolution in acoustical imaging is characterized by the spectral properties of the transducer used in an imaging system, with the center frequency determining the lateral resolution (together with the aperture size and the object distance) and the b

The theory of quantitative ultrasonic imaging places high demands on the data to be collected. When using imaging techniques in the field, restrictions have to be faced which are imposed by the physical limitations of transducers or by limits on comp

Since conventional single frequency acoustical holography provides only poor axial resolution, this concept was improved with the multifrequency holography to enhance the imaging quality. This leads to long data acquisition times because of the need
