Patent ID: 7181356

Claim:
A device for analyzing the structure of a material, comprising: a probe comprising a plurality of probe elements ( 5 ) for the emission of a wave, into the material, with an emission delay law corresponding to a deviation according to a direction and a focusing of this wave, and the reception, in parallel on the various probe elements ( 5 ), of signals originating from the refraction of this wave by the material, a plurality of emitters ( 7 ), each emitter ( 7 ) exciting a single probe element ( 5 ), a plurality of detection channels, each detection channel being connected to a probe element ( 5 ), so as to collect the refraction signals and transmit them to data processing means ( 4 ), a plurality of delay circuits ( 8 ), each delay circuit ( 8 ) applying a delay, to each detection channel, according to a predetermined reception delay law corresponding to the deviation of the wave emitted, characterized in that, each probe element ( 5 ) emits the wave with at least one other emission delay law corresponding to the emission of the wave according to at least one other deviation, simultaneously, and that the delay circuits apply delays to each detection channel according to at least one other predetermined reception delay law corresponding to the reception of the wave emitted according to the other deviation.
