Resonant Varifocal Mems Mirror

open access: yes2022 IEEE 35th International Conference on Micro Electro Mechanical Systems Conference (MEMS), 2022
This paper presents a novel varifocal mirror made of a micro-electromechanical system (MEMS) continuous deformable mirror (DM). It uses resonant electrostatic actuation (REA) via single voltage waveform to vary the focus of a 1.6 mm circular DM. Unlike traditional DMs, REA eliminates the need for individually addressable electrodes and the use of ...
