MAORY: A Multi-conjugate Adaptive Optics RelaY for ELT
Paolo Ciliegi, Guido Agapito, Matteo Aliverti +73
MAORY is the adaptive optics module for ELT providing two gravity invariant ports with the same optical quality for two different client instruments. It enable high angular resolut…
SPIRou: nIR velocimetry & spectropolarimetry at the CFHT
J. -F. Donati, D. Kouach, C. Moutou +63
This paper presents an overview of SPIRou, the new-generation near-infrared spectropolarimeter / precision velocimeter recently installed on the 3.6-m Canada-France-Hawaii Telescop…
New concepts for calibrating non-common path aberrations in adaptive optics and coronagraph systems
Francois Henault
Non Common Path Aberrations (NCPA) are often considered as a critical issue in Adaptive Optics (AO) systems, since they introduce bias errors between real wavefronts propagating to…
Hartmann vs. reverse Hartmann test: a Fourier optics point of view
Francois Henault, Cyril Pannetier
The Shack-Hartmann Wavefront Sensor (WFS) is well-known in the fields of optical metrology, wavefront sensing in astronomy, and ophthalmologic control applications. The purpose of…
Hi-5: a potential high-contrast thermal near-infrared imager for the VLTI
D. Defrère, M. Ireland, O. Absil +25
Hi-5 is a high-contrast (or high dynamic range) infrared imager project for the VLTI. Its main goal is to characterize young extra-solar planetary systems and exozodiacal dust arou…
Analysis of azimuthal phase mask coronagraphs
Francois Henault
In this paper is presented an analytical study of the azimuthal phase-mask coronagraph currently envisioned for detecting and characterizing extra-solar planets. Special emphasis i…
