A scanning system for writing, printing, direct imaging, plotting, computed radiography, and scanning includes an optical system contains at lest one modulatable radiation source for emitting radiation, a movable collimating lens, a reflector, and a focusing lens and a mechanical system containing a first mechanical carrier spinning about a first axis. A second mechanical carrier spins about a second axis. The second axis is mounted on the first mechanical carrier and is arranged to rotate about the first axis. A third mechanical carrier spins about a third axis. The third axis is mounted on the second mechanical carrier and is arranged to rotate about the second axis. The system also has a movable surface. The collimating lens is arranged to receive the radiation from the one radiation source and to convert it into at least one collimated beam which propagates along an optical path from the collimating lens to the surface via the reflector and the focusing lens to form at least one focused radiation spot on the surface. The mechanical system is arranged to cause the third mechanical carrier of the mechanical system to carry the reflector and the focusing lens of the optical system to move the one focused radiation spot on the surface along a straight line.
