Abstract

L'invention concerne des procédés de réduction des dimensions d'un faisceau lumineux incident de grandes dimensions ou d'agrandissement des dimensions d'un faisceau lumineux incident pour former un faisceau lumineux de grandes dimensions. Selon une variante, le procédé comprend l'envoi d'un premier faisceau lumineux (11) vers une lame partiellement réfléchissante (1) de dimensions adaptées aux dimensions du faisceau lumineux de grandes dimensions ; l'envoi sur un élément réflectif convergent (2) d'un deuxième faisceau lumineux (12) issu de la transmission à travers la lame partiellement réfléchissante du premier faisceau lumineux; l'envoi d'un troisième faisceau lumineux (13) issu de la réflexion sur l'élément réflectif convergent (2) du deuxième faisceau lumineux, vers ladite lame partiellement réfléchissante (1); la réflexion du troisième faisceau sur la lame partiellement réfléchissante pour former un quatrième faisceau lumineux (14).
