Zusammenfassung:Title screen
The high demands on the quality of the components of the International Thermonuclear Experimental Reactor(ITER) create the need to apply methods of nondestructive testing which are able to provide accurate andreliable results. One such technique is Digital Focus Array ultrasonic imaging with Matrix phased arrays. Theapplication of this approach is linked with the need to process huge sets of data in order to obtain images ofcontrolled objects. In this article, we propose the technique of computationally efficient Fourier-domain postprocessing.This algorithm is based on Fast Fourier transformations and calculations in frequency domains andcan be applied in immersion and contact testing. The performance of this technique was examined experimentally.
