From the ardent bucklers used during the Syracuse battle to set fire to Romans' ships to
more contemporary piezoelectric deformable mirrors widely used in astronomy, from very …

In this work, two advanced technologies were applied for manufacturing a bimorph
wavefront corrector: laser ablation, to vaporize conductive silver coating from piezoceramic …

Micro-Electro-Mechanical Systems (MEMS) Deformable Mirrors (DMs) enable precise
wavefront control for optical systems. This technology can be used to meet the extreme …

ULTIMATE-Subaru is a next facility instrumentation program of the Subaru Telescope. The
goal of this project is to extend the wide-field capability of the Subaru to near-infrared (NIR) …

ULTIMATE-Subaru is the next-generation facility instrument program of the Subaru
Telescope which will extend the existing Subaru's wide-field survey capability to the near …

Since Galileo's first observations in 1609, telescopes have grown dramatically in size.
Larger telescopes collect more light, allowing astronomers to detect fainter sources and to …

We present modeling and analysis of a hysteretic deformable mirror where the facesheet
interacts with a continuous layer of piezoelectric material that can be actuated distributively …

Future large adaptive telescopes will trigger new constraints for the calibration of adaptive
optics (AO) systems equipped with pre-focal deformable mirrors (DMs). The image of the DM …

The Multi-Conjugate Adaptive Optics module for the European Extremely Large Telescope
has been designed to achieve uniform compensation of the atmospheric turbulence effects …

Deformable mirrors are vital components of any adaptive optical system. Considering such a
crucial role in compensation of incident wavefront distortions, the main requirements are …
