Abstract
A device for treating an area of skin by scanning radiation to form a pattern of treatment spots on the skin may include a radiation source that generates an input beam, and a scanning system that scans the input beam to provide a sequential series of reflected output beams that form a pattern of treatment spots on the skin. The scanning system may include a rotating scanning element including a plurality of reflection surfaces, each configured to reflect the input beam in an angular direction to provide one of the reflected output beams, such that as the rotating scanning element rotates about an axis, the input beam is sequentially reflected by different reflection surfaces to provide the sequential series of reflected output beams, wherein a first reflection surface is offset from a second reflection surface in a direction generally along the axis of rotation of the rotating scanning element.
