Abstract

La présente invention concerne un procédé et un appareil optiques destinés à la mesure de propriétés d'un véhicule en déplacement ou d'une surface de déplacement sur laquelle se déplace le véhicule, le procédé consistant à envoyer une lumière incidente issue d'une source de lumière sur la surface de déplacement; recueillir la lumière réfléchie par la surface de déplacement; déterminer un décalage Doppler induit par la surface entre la lumière incidente et la lumière recueillie; et déterminer au moins une propriété de mouvement du véhicule en déplacement et une propriété de surface de la surface de déplacement en fonction du décalage Doppler induit par la surface qui a été déterminé.
