Abstract

L'invention concerne un dispositif de détection de défauts d'une structure (STR), le dispositif comprenant une unité de calcul et une pluralité de transducteurs (100) destinés à être positionnés sur ou dans la structure (STR), - des premiers transducteurs (E) de la pluralité de transducteurs (100) étant aptes à être dans un mode d'émission, - des seconds transducteurs (R) de la pluralité de transducteurs (100) étant aptes à être dans un mode de réception, caractérisé en ce que les premiers transducteurs (E) forment un maillage hexagonal de sorte à délimiter entre eux plusieurs mailles limitrophes entre elles, les seconds transducteurs (R) étant disposés sur des cercles d'émission respectifs des premiers transducteurs (E), chaque cercle d'émission d'un premier transducteur (E) étant centré sur le premier transducteur (E).The invention relates to a device for detecting defects in a structure (STR), the device comprising a calculation unit and a plurality of transducers (100) intended to be positioned on or in the structure (STR), - first transducers (E) of the plurality of transducers (100) being capable of being in a transmission mode, - second transducers (R) of the plurality of transducers (100) being capable of being in a reception mode, characterized in that that the first transducers (E) form a hexagonal mesh so as to delimit between them several bordering meshes between them, the second transducers (R) being arranged on respective emission circles of the first transducers (E), each emission circle of a first transducer (E) being centered on the first transducer (E).
