Apparatus for imaging anomalous ultrasonic wave propagation

PURPOSE: A deformed ultrasonic propagation imaging apparatus is provided to remotely collect ultrasonic wave generated from an object with high reproducibility at high speed using a pulse laser beam which is irradiated from a Q-switch CW laser. CONSTITUTION: A deformed ultrasonic propagation imaging apparatus(100) comprises a laser irradiating unit(120), a beam expander(160), a biaxial laser mirror scanner(130), a sensor(140), a first image processing controller(151), a second image processing controller(152), and an output unit(190). The laser irradiating unit irradiates a pulse laser beam. The beam expander controls the focus of the pulse laser beam. The biaxial laser mirror scanner controls the irradiation path of the pulse laser beam. The sensor senses the ultrasonic wave which is created by an object receiving the pulse laser beam. The first image processing controller comprises a bandpass filter letting only an ultrasonic signal of specific frequency band pass through. The second image processing controller eliminates the normal ultrasonic wave from the sensed ultrasonic wave and reconstructs a 3D ultrasonic wave structure using deformed ultrasonic wave. The output unit outputs the 3D ultrasonic wave structure created by the second image processing controller.

Avec une pluralité de capteurs (e.g. Bragg FBG et/ou de transducteurs piézoélectriques et/ou de transducteurs électromagnétiques acoustiques) déployés dans, sur ou à proximité de la structure, des capteurs sont interrogés et une fonction représentative de la réponse impulsionnelle de la structure est déterminée par filtre inverse passif. Par suite, il est déterminé une cartographie de la propagation des ondes élastiques dans la structure selon différentes modalités, et en particulier par tomographie (ondes de volumes ou guidées, par analyse du temps de vol ou selon le signal complet). Des développements décrivent notamment la gestion du nombre et de la position des capteurs, l'usage de sources artificielles de bruit, l'asservissement des capteurs et/ou des sources de bruit au contrôle de santé de la structure, ou encore la visualisation du comportement dynamique de la structure. The document describes methods and systems for the analysis of an industrial structure. With a plurality of sensors (eg Bragg FBG and / or piezoelectric transducers and / or acoustic electromagnetic transducers) deployed in, on or near the structure, sensors are interrogated and a function representative of the impulse response of the structure is determined by passive inverse filter. As a result, it is determined a mapping of the propagation of elastic waves in the structure according to different modalities, and in particular by tomography (volume or guided waves, by analysis of the flight time or according to the complete signal). Developments describe in particular the management of the number and position of the sensors, the use of artificial sources of noise, the slaving of the sensors and / or sources of noise to the health control of the structure, or the visualization of the behavior. dynamics of the structure.

MEANS AND METHOD FOR NON-UNIFORM POLARIZATION OF PIEZOELECTRIC TRANSDUCERS.

Moyen et procédé de polarisation non uniforme de transducteurs piézoélectriques comprenant la production par usinage d'une ou plusieurs indentations (34) dans une extrémité d'une tige piézoélectrique (28) et le découpage de la tige afin d'obtenir une forme de disque épais. Une ou plusieurs électrodes sont configurées de façon à s'adapter à emboîtement dans les indentations sur ladite face du disque, un nombre identique d'électrodes étant aptes à être positionnées sur la face opposée de la matière. Un courant électrique est ensuite appliqué aux électrodes, suivant la polarité et pendant une période de temps voulues. Les indentations font varier le champ électrique créé à l'intérieur de la matière piézoélectrique de façon à établir une polarisation non uniforme dans la matière. Le disque épais est ensuite découpé afin d'éliminer les indentations et d'obtenir un disque mince à deux côtés plats, destiné à être installé dans une sonde à transducteur piézoélectrique classique. Les indentations sont sélectionnées de façon à produire une polarisation conforme à des profils de réponse de transducteur voulus, tels que des fonctions de Gauss ou de Bessel. A means and method for non-uniform polarization of piezoelectric transducers comprising producing by machining one or more indentations (34) in one end of a piezoelectric rod (28) and cutting the rod to obtain a thick disc shape . One or more electrodes are configured so as to fit into the indentations on said face of the disc, an identical number of electrodes being able to be positioned on the opposite face of the material. An electric current is then applied to the electrodes, depending on the polarity and for a desired period of time. The indentations vary the electric field created within the piezoelectric material so as to establish a non-uniform polarization in the material. The thick disc is then cut in order to eliminate the indentations and obtain a thin disc with two flat sides, ...
