Abstract
A complementary scanning device control system was developed. In the system, the laser beam is displaced by deflectors inside the writing zone confined by the focusing objective field. The deflectors are placed in a scanning head that, in its turn, can move over the entire writing field. Based on the proposed control system model it is shown that the chosen system implementation allows precision image writing on formats that are much greater than the writing field of the focusing objective; the writing speed is primarily determined by the scanning head deflectors. Results of simulating the system behavior and experimental results are presented.
