Abstract
An optical orientation device includes a support structure; an optical element having an optical surface interacting with a laser beam; and a mechanism mounted on the support structure rotating the optical element around mutually perpendicular first and second fixed rotation axes. The mechanism includes a first rotary assembly articulated around a first mobile support axis, which is rotary and perpendicular relative to the first rotation axis. The first rotary assembly is coupled to the support structure to rotate around the first rotation axis, so the optical element rotates around the first rotation axis and the first mobile support axis. A second rotary assembly rotates around a second mobile support axis perpendicular to the first mobile support axis. The beam passes through a cavity around the first rotation axis, the cavity facing the optical element. First and second linear actuators rotate the first rotary assembly and the second rotary assembly, respectively.
