Abstract

Système optique de mesure en temps réel de la distribution spatiale de particules d~aérosol, telles que des pesticides, pulvérisées par un véhicule sur un champ agricole. Un capteur optique directement monté sur le véhicule émet un faisceau de lumière d~excitation à travers l~aérosol en cours de pulvérisation. La lumière diffusée qui en résulte est reçue et analysée pour en tirer des informations relatives à la distribution spatiale des particules. Ces informations sont transmises à un module de traitement qui génère alors des instructions de pulvérisation, telles qu~un signal d~avertissement, à l~intention du conducteur du système. L~invention permet donc de gérer en temps réel la pulvérisation de l~aérosol et d~éviter ainsi la contamination de zones sensibles.
