This work introduces a system and controller design
of an electromagnetically actuated fast steering mirror (FSM)
tailored for Lissajous trajectories. The proposed system enables
an improved performance in terms of energy consumption and
tracking precision. By individually tuning the stiffness of each
scan axis of the proposed FSM system, the resonance frequencies
are placed at the drive frequencies of the desired Lissajous
trajectory. The design of a dual tone controller for feedback
control is presented, matched to the scanning trajectory and the
tuned FSM dynamics. It is shown that compared to a state of
the art FSM system the energy consumption can be reduced by
a factor of 100 using the modified system structure and the dual
tone controller. Vice-versa the maximum scan area is enlarged by
a factor of 60. The resulting rms tracking error can be reduced
by 48% as compared to the conventional FSM system.
