Abstract

Elément de filtrage pour un faisceau de lumière cohérente, comportant un réseau de diffraction placé sur le trajet du faisceau, caractérisé en ce que ledit réseau 6 est disposé par rapport à la direction du faisceau 4 de façon que l'angle d'incidence de celui-ci, compatible avec la résolution recherchée, soit différent de l'angle de diffraction et en ce qu'il comporte en outre au moins un élément optique supplémentaire 8 placé sur le trajet d'une composante du faisceau diffracté par ledit réseau 6 et destiné à renvoyer sur celui-ci une partie de la lumière de ladite composante.
