Abstract

L'invention a trait à un appareil et à un procédé permettant d'imprimer des zones de bandes en deux dimensions sur un support photosensible, qui font appel à au moins un modulateur spatial de lumière à cristaux liquides réfléchissant. Dans ledit appareil et selon ledit procédé, des dispositifs optiques d'éclairage reçoivent de la lumière d'une source lumineuse, et imagent ladite lumière au niveau d'un élément diviseur de faisceau à polarisation. Ledit élément diviseur de faisceau à polarisation image un état de polarisation de ladite lumière au niveau du modulateur spatial de lumière, afin de générer un éclairage sensiblement collimaté au niveau du modulateur spatial de lumière.
