Abstract

L'invention concerne un dispositif d'éclairage permettant d'éclairer un objet plat (BN), par stries, qui contient un système de miroirs, disposé en section transversale, symétriquement à un axe optique (OA) et composé de plusieurs segments de miroir (S1,S2,S22,S3) se jouxtant mutuellement successivement. La segmentation du système de miroirs permet d'éviter des interférences indésirables dues aux reflets et à la lumière diffusée, de réduire la dépendance de l'intensité lumineuse dans le plan d'objet, à distance de l'objet, ainsi que la profondeur hors tout de l'ensemble du système.
