Abstract

L'invention concerne un appareil optique à laser produisant deux faisceaux laser rapprochés. Il comporte deux blocs 1, 2 d'émission laser qui produisent des faisceaux laser 3, 4 passant successivement par des lentilles 5, un miroir polygonal tournant 7, et des lentilles 8 et 9 pour atteindre un élément photosensible 10 sur lequel ils effectuent un mouvement de balayage sous l'action du miroir tournant 7. Les deux sources d'émission 1, 2 sont placées l'une derrière l'autre, le faisceau de la source 2 passant à travers une partie de la source 1. Domaine d'application : imprimantes à laser rapides, etc.
