Abstract

Procédé non-invasif de mesure d’une grandeur physique représentative de l’élasticité de la peau, comportant : - la détermination (86) des vitesses de phase du mode fondamental des différentes composantes d'une onde de cisaillement générée à la surface de la peau, le long d'un axe de mesure, l'ensemble des paires, formées chacune par une fréquence fi et la vitesse de phase Vi du mode fondamental déterminée pour cette fréquence fi, formant une courbe de dispersion du mode fondamental dans une direction de mesure parallèle à l'axe de mesure, où l'indice "i" est un numéro d'ordre de la fréquence fi et de la vitesse de phase Vi, et - la transformation (100) de cette courbe de dispersion en un profil de vitesses de phase en fonction de la profondeur, la vitesse de phase à une profondeur donnée étant une grandeur physique représentative de l'élasticité de la peau à cette profondeur.
