Application of Fourier-Domain Post-Processing Technique for Ultrasonic Imaging with Matrix Phased Arrays in Advanced Manufacturing of Details and Machines

Abstract

Quality of the components in the mechanical engineering is of the utmost importance. Most of quality control procedures can be provided by advanced quality assurance methods that enable visualization of inner structure of a component within all of the occurring defects. This paper suggests an innovative post-processing technique for Full-Matrix ultrasonic imaging with Matrix phased arrays in the case of immersion testing. Evaluation of the reliability was performed by simulation via CIVA software as well as by experimental testing of a real component with given defects. The obtained results of the research demonstrated high sensitivity and accuracy of the suggested technique.
