Abstract
Laser systems are provided that include a turntable having a plurality of circumferential mirrors that are rotatably controlled by one motor. One or more laser modules are oriented to direct laser beams at the mirrors, as the mirrors are rotated. Each beam that is reflected by a mirror forms a dot of the desired image. The vertical level of the formed dots is controlled either by providing the mirrors at different angles, or by providing a plurality of laser modules at differently angled orientations or at different vertical positions. The positioning of dots along a horizontal line is controlled by synchronizing the rate of rotation of the turntable with the on-off times of the laser module(s).
