Abstract

A nutating coupler arrangement is provided for driving an oscillating mirror movable about an axis of oscillation 12. A driving member 18, which rotates about a driving axis 24, is connected to the oscillating mirror through a coupler 28. The driving axis 24 is offset relative to the plane 34 perpendicular to the axis of oscillation 12 and extending through the pivotal point 30 of the coupler 28 at the oscillating mirror. The coupler 28 makes a nutating motion while the pivotal point 30 makes an oscillating motion.
