Abstract
Système de contrôle d’au moins un composant d’un élément optique L’invention a pour objet un système de contrôle d’un élément optique (2) ce système comprenant au moins : - un dispositif de support (3) de l’élément optique à contrôler, - un dispositif de projection (4) d’affichage d’une image lumineuse sur l’élément optique (2), - un dispositif d’acquisition (5) d’au moins une partie de l’image lumineuse ayant traversé l’élément optique (2) et issue de l’image lumineuse projetée, - une unité de calcul configurée pour déterminer la puissance optique de l’élément (2) contrôlé à partir, d’une part, d’au moins deux points d’au moins une image lumineuse projetée et, d’autre part, d’au moins deux points de l’image lumineuse acquise issue de l’image projetée et ayant traversé l’élément optique (2), le dispositif de projection (4) projetant une image illustrant une variation d’intensité lumineuse périodique disposée selon des franges parallèles et orientée selon un axe défini. Figure à publier avec l’abrégé : Fig. 4
