<p>The invention relates to a device for guiding a light beam with a light guiding element that is driven in a rotating or oscillating manner, the element having at least one optical group, which comprises at least two plane-parallel surfaces in an operational state, which are aligned at an inclination transversely to the light beam about an adjustable tilting angle. The invention further relates to a method for guiding a light beam, wherein a light beam is guided through an optical group having plane-parallel faces in at least one operational state. The optical group is moved continuously such that the direction of a surface normal of one of the planar faces of the optical group is changed periodically with respect to the optical axis.</p> |
