Abstract: Ce drone (10) comprend un capteur (40) de mesure des données représentatives, comportant au moins une cellule de mesure ouverte dans l'atmosphère, au moins une première source laser propre à injecter dans la cellule de mesure, un premier faisceau laser à une première longueur d'onde caractéristique d'un premier gaz à détecter et une deuxième source laser propre à injecter dans la cellule de mesure un deuxième faisceau laser à une deuxième longueur d'onde caractéristique d'un deuxième gaz à détecter. Le capteur de mesure (40) comporte un détecteur commun aux deux sources laser, propre à capter un premier signal de mesure provenant de la cellule de mesure et résultant de l'injection du premier faisceau laser dans la cellule de mesure et un deuxième signal de mesure provenant de la cellule de mesure et résultant de l'injection du deuxième faisceau laser dans la cellule de mesure.

Abstract: Various embodiments of the present disclosure provide systems and methods for detecting and classifying a disease state of a plant based at least in part on generating a reflectance signature for the plant. The reflectance signature is generated using a reduced set of orthogonal signal components determined from the Karhunen-Loeve Expansion. Various embodiments enable the classification of different disease states (e.g., healthy, asymptomatic, early stage, late stage) of a particular plant disease and the classification of disease states of different plant diseases, such as the differentiation between plants infected with a first plant disease from plants affected with another plant condition. The reflectance signature is generated using reduced-spectrum frequency data extracted or processed from reflectance signal data obtained from the plant. One or more signal components of the reflectance signal data that accurately describe at least a threshold amount of variance or energy of the reflectance signal data are selected for generation of the reflectance signature.
