ULTRASONIC SURFACE WAVE CONVERTER AND METHOD FOR MANUFACTURE THEREOF Russian patent published in 2014 - IPC H04R17/00 

FIELD: physics.

SUBSTANCE: ultrasonic surface wave converter comprises piezoelectric elements which can be connected to an ultrasonic flaw detector, an acoustic insulator, a housing, wherein the piezoelectric elements of the converter, which are polarised on the thickness, are mounted on one face perpendicular to the working surface, lie apart from each other by a distance greater than the spatial duration of a probing pulse (L>τc), are acoustically insulated from each other and are electrically connected together or separately with clock or synchronous connection.

EFFECT: designing a surface wave converter which enables to inspect metallic and non-metallic articles, having high efficiency and accuracy of determining coordinates and location of defects, as well as high resolution, having high inspection sensitivity, enabling adaptation when inspecting articles with a complex profile and limited access, which enables to detect differently oriented defects.
