Abstract

L'invention concerne un dispositif (1) et un procédé pour déterminer la vitesse du vent dans l'atmosphère. L'invention vise à permettre l'utilisation des rayonnements dispersés (S) de faible intensité pour déterminer la vitesse du vent. À cet effet, le dispositif (1) présente un filtre de longueurs d'onde optique (2) muni d'au moins une arête de filtre et au moins un détecteur (3) pour la détection du rayonnement dispersé (S) filtré.
