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.
