Abstract

L'invention concerne un dispositif de balayage bidimensionnel par laser. Il comporte essentiellement un analyseur polygonal tournant produisant un balayage dans la direction Y et un miroir tournant produisant un balayage dans la direction X. Le faisceau dévié est réfléchi vers un document à analyser à travers une lentille cylindrique qui se déplace en synchronisme avec le miroir tournant Le synchronisme des mouvements peut être assuré par un verrouillage mécanique ou par un verrouillage électronique. L'invention s'applique notamment aux machines de reprographie xérographique.
