MOYEN ACOUSTIQUE DE DETECTION, DE LOCALISATION ET D'EVALUATION AUTOMATIQUE D'IMPACTS SUBIS PAR UNE STRUCTURE

A device which detects and locates an impact on a structure. The device includes at least three acoustic sensors so that an acoustic wave emitted at any point of a measurement space can be received through direct propagation by each of the sensors. The device also includes command controller configu...

Summary:A device which detects and locates an impact on a structure. The device includes at least three acoustic sensors so that an acoustic wave emitted at any point of a measurement space can be received through direct propagation by each of the sensors. The device also includes command controller configured to process the signals corresponding to the acoustic waves received by the acoustic sensors, to detect the occurrence of an impact, and to locate a point of the structure that is the source of an acoustic wave. At least one optical pointer is actuated by the command controller so as to designate an impact point located on the structure by illuminating a corresponding site of the structure.
