Abstract (en)
[origin: WO2015075121A1] The invention relates to a method for reconstructing a profile of a part (10), using a transceiver device (12) including N elements, said device being suitable for transmitting a wave propagating in a medium, comprising at least the following steps: A) collecting the signals Si,j reflected by the part exposed to the wave; B) measuring the flight time of the surface echo tj for a plurality of transceiver pairs {E1,Rj}; C) building the family of ellipses Γc associated with said transmitter pairs {E1,Rj}; D) computing the envelope of the family of ellipses Γc; and E) from said envelope, determining the points Pi that make up the profile of the part.
