Figure 2From: Resonant-frequency tuning of angular vertical comb-driven microscannerNormalized mechanical and electrostatic moment of the AVC-driven microscanner with respect to the angular displacement. The electrostatic moment (bold black curve) is calculated by FEA, and a unit comb electrode set is used to account for the fringing fields. The mechanical restoring moment of the torsional spring is depicted for the torsional spring with (red line) and without (thin black line) an initial tilt angle.Back to article page
