Dynamic response of ferrofluidic deformable mirrors using elastomer membrane and overdrive techniques
Maxime Rochette, Ermanno F. Borra, Jean-Philippe Déry +1
Here are presented the experimental results obtained with a ferrofluidic deformable mirror controlled by electro-magnet actuators. Using a step input through a single actuator we o…
Optical properties of Au colloids self-organized into rings via copolymer templates
S. Lamarre, A. Sarrazin, J. Proust +4
The investigation of the Localized Surface Plasmon Resonance for plasmonic nanoparticles has opened new perspectives for optical nanosensors. Today, an issue in plasmonics is the d…
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 magnetic liquid deformable mirror for high stroke and low order axially symmetrical aberrations
Denis Brousseau, Ermanno F. Borra, Hubert-Jean Ruel +1
We present a new class of magnetically shaped deformable liquid mirrors made of a magnetic liquid (ferrofluid). Deformable liquid mirrors offer advantages with respect to deformabl…
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…
Optical Tests of Nanoengineered Liquid Mirrors
Helene Yockell-Lelievre, Ermanno F. Borra, Anna Ritcey +1
We describe a new technology for the fabrication of inexpensive high-quality mirrors. We begin by chemically producing a large number of metallic nanoparticles coated with organic…
