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…
A cryogenic liquid-mirror telescope on the moon to study the early universe
Roger Angel, Simon P. Worden, Ermanno F. Borra +9
We have studied the feasibility and scientific potential of zenith observing liquid mirror telescopes having 20 to 100 m diameters located on the moon. They would carry out deep in…
GH FaS : Galaxy H-alpha Fabry-Perot System for the WHT
O. Hernandez, K. Fathi, C. Carignan +11
GHFaS a new Fabry-Perot system, is now available at the William Herschel Telescope. It was mounted, for the first time, at the Nasmyth focus of the 4.2 meter WHT on La Palma in…
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…
