ACOUSTIC ANTENNA AND METHOD OF ITS OPERATION Russian patent published in 2020 - IPC G01N29/04 

FIELD: acoustics.

SUBSTANCE: invention can be used for non-destructive acoustic control of an object. Essence of the invention consists in the fact that the acoustic antenna with dry point contact of the piezoelectric transducers with the surface of the monitored object comprises a substrate, made with possibility of fixation on the surface of the monitored object, clamping device of piezoelectric transducers and software and hardware complex electrically connected to the piezoelectric transducers of the antenna, wherein substrate is flexible with parallel slots, and piezoelectric transducers are connected in several detachable modules of antenna arrays, installed in these slots, are made transceiving and are able to be activated both in series and with time delay t, wherein the clamping device is made in the form of magnetic conductors, installed in detachable modules of piezoelectric transducers.

EFFECT: increased probing zone.
