Abstract

L'invention concerne un système pour distribuer une lumière depuis une source de lumière vers un dispositif de micro-miroir numérique. Le système comprend un ou plusieurs groupes de lentilles. Au moins une lentille du système est déplacée latéralement, de sorte que son axe optique ne soit pas centré sur le rayon principal du système.
