Autor: Kairui Cao, Guanglu Hao, Qingfeng Liu, Liying Tan, Jing Ma

Publikováno v: Micromachines, Vol 12, Iss 7, p 732 (2021)

Fast steering mirrors (FSMs), driven by piezoelectric ceramics, are usually used as actuators for high-precision beam control. A FSM generally contains four ceramics that are distributed in a crisscross pattern. The cooperative movement of the two ce
