Abstract

L'invention concerne un procédé et un système de lentilles (1) pour réunir des rayons de lumière (3, 4) provenant de diverses directions, en un foyer (7), et pour transformer ces rayons en lumière parallèle (4) si nécessaire, pour les transmettre au moyen de photoconducteurs (6) et/ou les guider vers une autre utilisation. Des points lumineux différents sont superposés dans un espace pour former un foyer (7). Ce processus peut en théorie être répété à l'infini. Il est ainsi possible de concentrer de très grandes quantités de lumière.
