CA 2461721

A method and apparatus to illuminate a target. The apparatus can comprise a first lens (30) configured to receive light from the light source (10), a diffractive optical element (40) configured to receive the light from the first lens and to regulate the light into regulated light (50), and second lens (60) configured to receive the regulated light and to direct the regulated light onto a selected area of the target (70).

L'invention concerne un procédé et un dispositif permettant d'illuminer une cible. Le dispositif peut comporter une première lentille (30) conçue pour recevoir la lumière issue de la source lumineuse (10), un élément optique à diffraction (40) conçu pour recevoir la lumière provenant de la première lentille et pour assurer une régulation donnant une lumière régulée (50), et enfin une seconde lentille (60) conçue pour recevoir cette lumière régulée et pour l'orienter vers une zone déterminée de la cible (70).
