Abstract
(EN) A scanning beam system using a rotating platform driven by a motor, and a prism and/or mirror assembly mounted to the rotating platform. In some embodiments, the prism is a square prism. In some embodiments the prism is of polygon shape other than a square. In some embodiments, the mirror assembly is a square mirror assembly. In some embodiments the mirror assembly is of polygon shape other than a square. In some embodiments the mirror assembly includes a plurality of reflective faces, each at a different angle relative to an axis of rotation of the rotating platform.
(FR) L'invention concerne un système de faisceau de balayage utilisant une plate-forme rotative entraînée par un moteur, et un ensemble prisme et/ou miroir monté sur la plate-forme rotative. Dans certains modes de réalisation, le prisme est un prisme carré. Dans certains modes de réalisation, le prisme est de forme polygonale autre qu'un carré. Dans certains modes de réalisation, l'ensemble miroir est un ensemble miroir carré. Dans certains modes de réalisation, l'ensemble miroir est de forme polygonale autre qu'un carré. Dans certains modes de réalisation, l'ensemble miroir comprend une pluralité de faces réfléchissantes, chacune à un angle différent par rapport à un axe de rotation de la plate-forme rotative.
