A novel high-speed piezoelectric deformable varifocal mirror for optical applications

Technical Digest. MEMS 2002 IEEE International Conference. Fifteenth IEEE International Conference on Micro Electro Mechanical Systems (Cat. No.02CH37266), 2003
We describe the characteristics of a microelectromechanical deformable optical component: a parabolic focusing mirror having a focal length that is controlled by piezoelectric actuation of thin-film PZT. Devices of two different sizes were tested and have resonant frequencies in the low MHz range, nominal focal lengths between 1500 and 2000 /spl mu/m ...

Hysteresis compensation of piezoelectric deformable mirror based on Prandtl–Ishlinskii model

Optics Communications, 2018
Abstract Hysteresis of piezoelectric deformable mirror (DM) reduces the closed-loop bandwidth and the open-loop correction accuracy of adaptive optics (AO) systems. In this work, a classical Prandtl–Ishlinskii (PI) model is employed to model the hysteresis behavior of a unimorph DM with 20 actuators.

Hard X-ray nanofocusing using adaptive focusing optics based on piezoelectric deformable mirrors

Review of Scientific Instruments, 2015
An adaptive Kirkpatrick–Baez mirror focusing optics based on piezoelectric deformable mirrors was constructed at SPring-8 and its focusing performance characteristics were demonstrated. By adjusting the voltages applied to the deformable mirrors, the shape errors (compared to a target elliptical shape) were finely corrected on the basis of the mirror ...

Performance of a thermal-piezoelectric deformable mirror under 62  kW continuous-wave operation

Applied Optics, 2013
The thermal-piezoelectric deformable mirror (TPDM) is a device employed to compensate for laser-induced mirror deformation and thermal lensing in high-power optical systems. The TPDM setup is a unimorph deformable mirror with thermal and piezoelectric actuation properties. Laser-induced thermal lensing is compensated for by heating of the TPDM. We show
