Annular Phased Array Dynamic Focusing Method for Large Target Ultrasonic Testing

Ferroelectrics, 2014
A novel method called dynamic focusing immersed ultrasonic testing (DFIUT) is proposed which utilizes an annular phased array ultrasonic transducer (APAUT) and one of the distinguished advantages is dynamic focusing. The proposed DFIUT is aimed at solving the focus deviation problem in the detection of large targets. The design methodology of APAUT and

Comparison of systems for ultrasonic nondestructive testing using antenna arrays or phased antenna arrays

Russian Journal of Nondestructive Testing, 2013
This paper considers the features of forming the images of reflectors using phased antenna array technology and the images obtained by the C-SAFT method by echo signals measured in by double-scanning mode. It is shown that in some cases the images obtained by the phased antenna array technology are less informative, while the images obtained by the C ...
