Mirror Deformation by Piezoelectric Actuators
IEEJ Transactions on Sensors and Micromachines, 2006 Recently, MEMS devices are being studied for which the focus can be changed by moving a lens. Therefore, we propose a MEMS-based varifocal mirror in which piezoelectric actuators are used. In this study, we used micromachining to fabricate a varifocal mirror by bonding bulk PZT to Si single crystals, and then evaluated its performance.

Robust control of a bimorph mirror for adaptive optics system [PDF]
, 2008 We apply robust control technics to an adaptive optics system including a dynamic model of the deformable mirror. The dynamic model of the mirror is a modification of the usual plate equation. We propose also a state-space approach to model the turbulent

Thermal Balance and Active Damping of a Piezoelectric Deformable Mirror for Adaptive Optics
Actuators, 2019 Piezoelectric unimorph deformable mirrors offer a cheap solution to adaptive optics, with mass production capability. However, standard solutions have significant drawbacks: (i) the static shape is sensitive to the temperature, and (ii) the low ...
