Title (EN) ELECTRICAL TOMOGRAPHY FOR VERTICAL PROFILING
(FR) TOMOGRAPHIE ÉLECTRIQUE DE PROFILAGE VERTICAL
Abstract:
(EN) An apparatus (600) for determining, by electrical tomography, vertical profile of an electrical property of interest of material(s) in a target volume (618) comprises a measurement probe (610) to be positioned at a plurality of different measurement levels (650) in a target volume and comprising a plurality of measurement elements (111) each having an interface surface (112). Each interface surface has a size, shape, and rotational position. A measurement path (114) is formed between two interface surfaces as dependent on the sizes, shapes, and rotational positions of the two interface surfaces, and the distance between the two interface surfaces. The locations, rotational positions, shapes, and sizes of the interface surfaces are selected to provide at least two different measurement paths differing from each other in one or more of said sizes of, shapes of, rotational positions of, and distances between the associated interface surfaces.
(FR) L'invention concerne un appareil (600) permettant de déterminer, par tomographie électrique, un profil vertical d'une propriété électrique d'intérêt d'un ou plusieurs matériaux dans un volume cible (618) comprenant une sonde de mesure (610) à positionner à une pluralité de niveaux de mesure différents (650) dans un volume cible et comprenant une pluralité d'éléments de mesure (111) possédant chacun une surface d'interface (112). Chaque surface d'interface présente une dimension, une forme et une position de rotation. Un trajet de mesure (114) est formé entre deux surfaces d'interface en fonction des dimensions, des formes et des positions de rotation des deux surfaces d'interface et de la distance entre les deux surfaces d'interface. Les emplacements, les positions de rotation, les formes et les dimensions des surfaces d'interface sont sélectionnés afin de fournir au moins deux trajets de mesure différents différant l'un de l'autre par rapport auxdites tailles, formes, positions de rotation et/ou distances entre les surfaces d'interface associées.
