Development of large aperture elements for active and adaptive optics

EPJ Web of Conferences, 2013
Large-aperture elements for laser active and adaptive optics are investigated in collaboration within IOP AcSci CR, FEng CTU and 5M. A bimorph deformable mirror for high-power lasers based on a lightweight structure with a composite core is currently ...

ADAPTIVE OPTICS WITH SEGMENTED MIRROR OR DEFORMABLE MIRROR

Le Journal de Physique Colloques, 1980
Two kinds of adaptive optics (COAT) are presented : one with segmented mirrors (COAT = 19) with 19 mirrors and actuators and the other with a continuously deformable mirror and 7 actuators. Each mirror of COAT 19 is moved by a piezoelectric actuator performing correction and modulation (dithering in the 12-24 kHz band).

Modeling and evaluation of magnetic fluid deformable mirror with dual-layer actuators

International Journal of Optomechatronics, 2019
In this paper, a rectangular magnetic fluid deformable mirror (MFDM) with dual-layer actuators is proposed, which is designed to improve the correction performance for full-order aberrations.

Development of a line module type of SiC deformable mirror

International Journal of Optomechatronics
In this work, the complete development of a line module type silicon carbide (SiC) deformable mirror (DM) for adaptive optics (AO) is described. To eliminate the risk of fracture and misalignment during the simultaneous assembly of all actuators and the ...

Design analysis of future deformable mirrors

, 2022
Adaptive optics systems are essential in ground-based astronomical observatories and in laser communication through free space. In particular, turbulence in the atmosphere causes wavefront aberrations that set a limit on the achievable image quality.

Astronomical adaptive optics: a review

PhotoniX
Since the concept of adaptive optics(AO) was proposed in 1953, AO has become an indispensable technology for large aperture ground-based optical telescopes aimed at high resolution observations.
