Abstract

Ensemble tête optique, procédé et procédure permettant de produire des faisceaux (201) de lumière multiples et de les placer avec précision pour qu'ils atteignent une cible. Ledit système diffracte une source de lumière d'entrée en un motif à faisceaux (215) de lumière multiples, ou produit initialement un motif de faisceaux de lumière multiples dans lequel les faisceaux individuels du motif à faisceaux (215) de lumière multiples sont précisément espacés, corrigés, concentrés et dirigés à travers un plan (222, 223) à deux axes vers la cible, avec un mouvement minimal des composants de l'ensemble tête optique. Ces faisceaux individuels peuvent également être modulés séparément.
