Abstract

Dispositif permettant de rendre symétrique le rayonnement produit par un ou plusieurs émetteurs optiques linéaires, en particulier des diodes laser à large bande. Ledit dispositif possède, par émetteur (1, 1a, 1b), une optique (2, 2a, 2b) possédant une ou plusieurs lentilles cylindriques qui collimatent chaque faisceau de rayons dans le sens y. Par une rotation d'au moins une des lentilles cylindriques autour de l'axe z ou par mise en place d'un élément de déviation discontinu, chaque faisceau de rayons est dévié selon des angles de déviation différents dans le sens y. Ledit dispositif comporte en outre une optique de collimation et de direction (3) qui collimate chaque faisceau de rayons dans le sens x et le dévie avec des angles de déviation différents, si bien que les rayons principaux des divers faisceaux de rayons coïncident dans le sens x à une distance définie de l'émetteur et s'étendent de manière parallèle dans le sens y. Ledit dispositif comporte enfin une optique de redirection (4) qui compense, dans le sens x, la déviation des faisceaux de rayons, provoquée par l'optique de collimation et de direction (3).
