| 摘要 |
A MEMS hierarchically-dimensioned deformable mirror comprising a substrate, a plurality of spacers disposed on the substrate, a plurality of piezoelectric cantilever microactuators disposed on the plurality of spacers, and a continuous deformable membrane disposed on the plurality of the cantilever assemblies, has significantly improved overall device performances owing to the use of the cantilever microactuators based on relaxor ferroelectric single crystal materials or other piezoelectric materials. |
