Operational Principles
Electrostatic Actuation
Electrostatic actuation is a primary mechanism used to control MEMS mirrors. It operates by creating an electric field between the fixed and movable parts of the device. This field generates a force that results in the movement of the mirror. The key characteristic that makes electrostatic actuation so beneficial is its efficiency in converting electrical energy into mechanical motion. This efficiency translates to rapid response times, allowing for high-speed applications in various fields.
One unique feature of electrostatic actuation is its ability to function without any moving parts beyond the mirror itself. This creates fewer points of failure, enhancing the reliability of the device. However, there are disadvantages, including the necessity for high voltage levels, which can complicate the design and limits some applications. Nonetheless, electrostatic actuation remains a popular choice due to its benefits in precision control and rapid response.
Piezoelectric Actuation
Piezoelectric actuation provides an alternative mechanism for driving MEMS mirrors. This method relies on piezoelectric materials, which change shape when an electric field is applied. This transformation allows for precise control over the mirror's position. The key characteristic of piezoelectric actuation is its ability to generate significant displacement with relatively low power.
