The ANTARES Collaboration: Contributions to ICRC 2017 Part III: Searches for dark matter and exotics, neutrino oscillations and detector calibration
ANTARES Collaboration, A. Albert, M. André +125
Papers on the searches for dark matter and exotics, neutrino oscillations and detector calibration, prepared for the 35th International Cosmic Ray Conference (ICRC 2017, Busan, Sou…
Optimal correction of distortion for High Angular Resolution images. Application to GeMS data
A. Bernard, B. Neichel, L. M. Mugnier +1
Whether is ground-based or space-based, any optical instrument suffers from some amount of optical geometric distortion. Recently, the diffraction-limited image quality afforded by…
Modelling astronomical adaptive optics performance with temporally-filtered Wiener reconstruction of slope data
Carlos M. Correia, Charlotte Z. Bond, Jean-François Sauvage +3
We build on a long-standing tradition in astronomical adaptive optics (AO) of specifying performance metrics and error budgets using linear systems modeling in the spatial-frequenc…
Combining freeform optics and curved detectors for wide field imaging: a polynomial approach over squared aperture
Eduard Muslimov, Emmanuel Hugot, Wilfried Jahn +5
In the recent years a significant progress was achieved in the field of design and fabrication of optical systems based on freeform optical surfaces. They provide a possibility to…
Iterative wave-front reconstruction in the Fourier domain
Charlotte Z. Bond, Carlos M. Correia, Jean-François Sauvage +2
The use of Fourier methods in wave-front reconstruction can significantly reduce the computation time for large telescopes with a high number of degrees of freedom. However, Fourie…
