Modeling framework for piezoelectrically actuated MEMS tunable lenses
Abdelmeguid, Mahmoud Ahmed Farghaly; Akram, Muhammad Nadeem; Halvorsen, Einar (Peer reviewed; Journal article, 2016)We report a modeling framework for evaluating the performance of piezoelectrically actuated MEMS tunable lenses. It models the static opto-electromechanical coupling for symmetric configurations of piezoelectric actuators ... -
Optical performance of piezoelectrically actuated MEMS tunable lenses with various pupil geometries
Abdelmeguid, Mahmoud Ahmed Farghaly; Akram, Muhammad Nadeem; Halvorsen, Einar (Journal article; Peer reviewed, 2017)Abstract. A square geometry for the diaphragm of microelectromechanical systems (MEMS) tunable lenses with circular pupils is often used. This square diaphragm introduces aberrations that would not be present for a circular ...
