The article proposes and analyzes a non-symmetric two-dimensional micro-motion mechanism with displacement amplification, driven by piezoelectricity and incorporating a planar capacitance sensor for displacement measurement, to improve the coupling efficiency between spatial light and fiber arrays.
Summary
The article proposes a non-symmetric, piezoelectric-driven two-dimensional micro-motion mechanism with displacement amplification for improving the coupling efficiency between spatial light and fiber arrays. The design incorporates flexible hinges and a planar capacitance sensor (PCS) for displacement measurement and motion decoupling. Simulation analysis verifies the feasibility of the design, showing a maximum single-direction travel of 125 μm and a two-dimensional travel of 177 μm, with an inherent frequency greater than 500 Hz. The mechanism aims to meet the high precision and large adjustment range requirements for fiber array coupling in retro-modulation based space division multiple access wireless laser communication technology.
