Figure 7
(Left) Dynamic evolution of the bimorph mirror's surface profile, measured at 100 ms intervals over a few seconds, before, during and after applying a single piezo response impulse of 400 V to a central electrode. (Right) For the first 1.3 s after T = 0 s, voltage (applied at a slew rate of 300 V s−1) is linearly applied which causes a corresponding linear change in the mirror curvature. After this time, the surface stabilizes with small residual drifts in the curvature. |
