Abstract
An illumination system includes a light source arranged for emitting non-collimated light towards a reflective surface of a scanning mirror assembly such that the light source occludes a region of the light reflected from the reflective surface. The scanning mirror assembly includes the reflective surface, which is arranged to be rotationally displaced around at least one rotation axis. The illumination system also includes an optical element for changing the propagation direction of the said reflected light so as to illuminate at least a part of the said occluded region.
