Design of the HARMONI Pyramid WFS module
Noah Schwartz, Jean-François Sauvage, Edgard Renault +12
Current designs for all three extremely large telescopes show the overwhelming adoption of the pyramid wavefront sensor (P-WFS) as the WFS of choice for adaptive optics (AO) system…
NAOMI: the adaptive optics system of the Auxiliary Telescopes of the VLTI
Woillez J., Abad J. A., Abuter R. +80
The tip-tilt stabilisation system of the 1.8 m Auxiliary Telescopes of the Very Large Telescope Interferometer was never dimensioned for robust fringe tracking, except when atmosph…
Sensing and control of segmented mirrors with a pyramid wavefront sensor in the presence of spiders
Noah Schwartz, Jean-François Sauvage, Carlos Correia +9
The segmentation of the telescope pupil (by spiders & the segmented M4) create areas of phase isolated by the width of the spiders on the wavefront sensor (WFS), breaking the spati…
The adaptive optics modes for HARMONI: from Classical to Laser Assisted Tomographic AO
B. Neichel, T. Fusco, J. -F. Sauvage +25
HARMONI is a visible and NIR integral field spectrograph, providing the E-ELT's core spectroscopic capability at first light. HARMONI will work at the diffraction limit of the E-EL…
MACAO-CRIRES, a step towards high-resolution spectroscopy
J. Paufique, P. Biereichel, R. Donaldson +14
High resolution spectroscopy made an important step ahead 10 years ago, leading for example to the discovery of numerous exoplanets. But the IR did not benefit from this improvemen…
On-sky results of the adaptive optics MACAO for the new IR-spectrograph CRIRES at VLT
J. Paufique, P. Biereichel, B. Delabre +16
The adaptive optics MACAO has been implemented in 6 focii of the VLT observatory, in three different flavors. We present in this paper the results obtained during the commissioning…
