Abstract

La présente invention concerne un procédé de mesure vélocimétrique d'une cib le (6) vibrant avec un déplacement supérieur à la longueur d'onde, avec une extension limitée autour d'une position moyenne, consistant à faire interfér er dans un matériau holographique (4) un faisceau laser de référence (3) et un faisceau diffusé (14) par la cible (6). On mesure à l'aide d'un détecteur photoélectrique (8) la variation d'intensité lumineuse transmise par le matériau.
