The invention relates to a device that is used to analyse the structure of
a material. The inventive device comprises: probe elements (5) which are
used to (i) emit a wave, in the material, with emission delay laws that
correspond to several simultaneous deviations and (ii) receive, on the
different probe elements (5), signals from the refraction of said wave by
the material; detection channels, each detection channel being connected
to a probe element (5), in order to collect the refraction signals and to
transmit same to data processing means (4); and delay circuits that apply
a delay on each detection channel according to the reception delay laws
which are predetermined and which correspond to the different deviations
of the wave emitted. The invention also relates to an analysis method
which can be used, in particular, on said device.
