A pattern generation system includes an optical system (106) and a rotor (100). The optical system (106) is configured to project a laser image onto an optical scanner c(104). The rotor (100) has a plurality of optical arms (102) arranged at a first angle relative to one another, and further includes the optical scanner (104). The laser image is sequentially reflected by the optical scanner (104) into each of the plurality of optical arms (102) of the rotor (100) to generate a pattern on a workpiece.
