Abstract

La présente invention concerne un dispositif d'aide perceptive pour l'inspection visuelle de HLB en champ, comprenant un filtre de lumière appliqué sur un substrat. Ce dispositif intensifie le contraste entre la couleur verte et la couleur jaune, caractéristique du "tachage" des feuilles, de manière à faciliter l'identification de la maladie par l'inspecteur de HLB. Par ailleurs, le dispositif bloque les rayons ultraviolets, offrant à l'utilisation une protection contre la lumière du soleil et un confort visuel pour l'exécution de son activité. L'invention concerne également le procédé d'incorporation du filtre de lumière dans le substrat, qui s'effectue par immersion du substrat dans le courant approprié avec des paramètres contrôlés, ainsi que l'utilisation du dispositif dans l'inspection visuelle de HLB ou de greening dans le champ.
