Wavefront correction with a ferrofluid deformable mirror: experimental results and recent developments
Denis Brousseau, Ermanno F. Borra, Simon Thibaul +7
We present the research status of a deformable mirror made of a magnetic liquid whose surface is actuated by a triangular array of small current carrying coils. We demonstrate that…
Nanoengineered Astronomical Optics
E. F. Borra, A. M. Ritcey, R. Bergamasco +5
We describe a technology for the fabrication of inexpensive and versatile mirrors through the use of a new type of nanoengineered optical material composed by the spreading of a se…
Ferrofluid Based Deformable Mirrors - a New Approach to Adaptive Optics Using Liquid Mirrors
P. Laird, R. Bergamasco, V. Berube +7
The trend towards ever larger telescopes and more advanced adaptive optics systems is driving the need for deformable mirrors with a large number of low cost actuators. Liquid mirr…
Ultra-Thin Floating Mirrors
Ermanno F. Borra, Anna Ritcey, Etienne Artigau
We discuss a new technology that promises large inexpensive mirrors. We argue that it should be possible to tilt a rotating viscous liquid by perhaps as much as a few tens of degre…
