Validation of a new adaptive deformable mirror concept
Roger Hamelinck,Rogier Ellenbroek,Nick Rosielle,M Maarten Steinbuch,Michel Verhaegen,Niek Doelman +5 more
TL;DR: A new prototype adaptive deformable mirror for future AO-systems is presented that consists of a thin continuous membrane on which push-pull actuators impose out-of-plane displacements.
Proceedings ArticleDOI
Distributed control in adaptive optics: Deformable mirror and turbulence modeling
Rogier Ellenbroek,Michel Verhaegen,Niek Doelman,Roger Hamelinck,Nick Rosielle,M Maarten Steinbuch +5 more
TL;DR: In this paper, a distributed framework is introduced in which each actuator has a separate processor that can communicate with a few direct neighbors, and the wavefront reconstruction step is fitted into the distributed framework such that the computational complexity for each processor increases only linearly with the telescope diameter.
Proceedings ArticleDOI
Large adaptive deformable membrane mirror with high actuator density
TL;DR: In this article, an adaptive deformable mirror concept is presented, which consists of a thin (30-50 μm) highly reflective, deformable membrane and is supported by an optimized light and stiff honeycomb sandwich structure.
Proceedings ArticleDOI
The opto-mechanical performance prediction of thin mirror segments for E-ELT
TL;DR: In this article, the design and analysis of the design features within the support structure to minimize the mirror deformation due to gravity is discussed. But the authors focus on the design of the mirror segments.
Proceedings ArticleDOI
Meeting highest performance requirements for lowest price and mass for the M1 segment support unit for E-ELT
TL;DR: The E-ELT as mentioned in this paper is the largest optical telescope in the world with a primary mirror of 42m in diameter and consists of 984 hexagonal segments that are all individually supported.
