The mirror plate of the microscanner performs a continuous, harmonic oscillation. The oscillation is excited electrostatically and utilizes planar electrostatic comb drives. The oscillation-frequency has to be close to the natural frequency of the scanning axis. Adjusting the driving voltage or the driving frequency allows setting and controlling the
oscillation amplitude. For 2D devices, the mirror plate is gimbal-mounted. The resonance frequency of each axis is determined by design independently. Each axis is excited individually. Thus, the ratio of the oscillation amplitudes and the phase difference can be set and controlled arbitrarily.
