Abstract

L'invention concerne un dispositif (1) optique pour la détermination d'une vitesse VT(t) d'une cible comportant : - un capteur interférométrique à rétro-injection optique (10) pour générer un signal interférométrique, ledit signal interférométrique SM(t) comportant l'information sur la vitesse de la cible, - des moyens de traitement (15) du signal interférométrique, reliés au capteur interférométrique à rétro-injection optique (10), comportant : - des moyens de conversion (16) pour convertir le signal interférométrique SM(t) en un signal logique à deux états, - des moyens de calcul (17), en sortie des moyens de conversion (16), pour déterminer la vitesse VT(t) de la cible à partir du signal logique. L'invention est également relative au procédé associé.
