    摘要: A method for mapping fibrous media by ultrasound propagation from a set (2) of transducers, which involves emitting a plurality of unfocused incident waves having different wave fronts, capturing the signals reverberated by the medium to each transducer, determining coherent signals corresponding respectively, for each transducer, to the contributions coming from various virtual focal points in the medium, then determining the orientation of the fibres by comparing the spatial coherence between said coherent signals, in a plurality of directions.
