Adaptive PVDF piezoelectric deformable mirror system

Applied Optics, 1980
An adaptive mirror system whose surface deforms smoothly according to the desired curve has been made of polyvinylidene fluoride (PVDF) piezoelectric film and laminar glass plate. One surface of the glass plate was evaporated with silver, and this side was used as the mirror surface. A PVDF film, whose shape was determined by the deformation curve, was

Development of piezoelectric MEMS deformable mirror

Microsystem Technologies, 2011
This paper reports on piezoelectric micro-electro-mechanical systems deformable mirrors with high-density actuator array for low-voltage and high-resolution retinal imaging with adaptive optics. The deformable mirror was composed of unimorph structure of lead zirconate titanate (PZT) thin film deposited on Pt-coated silicon on insulator substrate and a

Unimorph piezoelectric deformable mirrors for space telescopes

SPIE Proceedings, 2016
We have developed, manufactured and tested a unimorph deformable mirror for space applications based on piezoelectric actuation. The mirror was designed for the correction of low-order Zernike modes with a stroke of several tens of micrometers over a clear aperture of 50 mm.

Adaptive deformable mirror with piezoelectric ceramic actuators

Soviet Journal of Quantum Electronics, 1988
An experimental investigation was made of the formation of the relief of a reflecting surface by an adaptive deformable mirror. The additivity of the effect of a system of discrete actuators on the reflecting surface of the adaptive mirror was confirmed.
