Abstract
We have developed compact devices to control electrostatically driven resonant micromirrors with one and two axes. For stable oscillation with large amplitude, operation close to resonancemust be ensured under varying environmental conditions. Our devices feature optical position sensing and driver electronics with closed loop control. In this contribution, we present in much detail the novel two-dimensional device and highlight specific aspects of this system.
