Characterization and training of a piezoelectric deformable mirror for operation at 1550 nm
SPIE Proceedings, 2009Characterizing the fundamental response and operational parameters of a deformable mirror is a critical first step in the design of an adaptive optics system. This paper describes the characterization of the influence function and training of a piezoelectric deformable mirror (PDM) at 632 nm.

A piezoelectric deformable mirror for intra-cavity laser adaptive optics
SPIE Proceedings, 2008This paper describes the development of a deformable mirror to be used in conjunction with diffractive optical elements inside a laser cavity. A prototype piezoelectric unimorph adaptive mirror was developed to correct for time dependent phase aberrations to the laser beam, such as those caused by thermal expansion of materials.

Piezoelectric MEMS deformable mirrors with high-density actuator array
2011 IEEE 24th International Conference on Micro Electro Mechanical Systems, 2011We fabricated piezoelectric MEMS deformable mirror (DM) with high-density actuator array for adaptive optics to realize low-voltage and high-resolution retinal imaging. 61-element actuator array composed of lead zirconate titanate (PZT) thin film was deposited on the mirror diaphragm, and the diaphragm was deformed by applying control voltage onto the ...

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), 2003We 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 ...
