Simulation of Wavefront-based Disturbance Observers for Large Telescopes
Pascal Jaufmann, Aaron Buck, Marco Zaiser +2
The performance of future observatories such as the Extremely Large Telescope is mainly limited by atmospheric turbulence and structural vibrations of the optical assembly. To furt…
The MICADO first light imager for the ELT: off-axis performance of PSF reconstruction
Matteo Simioni, Daniel Jodlbauer, Carmelo Arcidiacono +14
The highest scientific return, for adaptive optics (AO) observations, is achieved with a reliable reconstruction of the PSF. This is especially true for MICADO@ELT. In this present…
P-REx II. Off-line Performance on VLTI/GRAVITY
Saavidra Perera, Jörg-Uwe Pott, Julien Woillez +4
For sensitive optical interferometry, it is crucial to control the evolution of the optical path difference (OPD) of the wavefront between the individual telescopes of the array. T…
Lessons learned from SPHERE for the astrometric strategy of the next generation of exoplanet imaging instruments
A. -L. Maire, M. Langlois, P. Delorme +14
Measuring the orbits of directly-imaged exoplanets requires precise astrometry at the milliarcsec level over long periods of time due to their wide separation to the stars ($\gtrsi…
On-sky results for the novel integrated micro-lens ring tip-tilt sensor
Philipp Hottinger, Robert J. Harris, Jonathan Crass +16
We present the first on-sky results of the micro-lens ring tip-tilt (MLR-TT) sensor. This sensor utilizes a 3D printed micro-lens ring feeding six multi-mode fibers to sense misali…
Photonics-based mid-infrared interferometry: 4-year results of the ALSI project and future prospects
L. Labadie, S. Minardi, J. Tepper +7
In this contribution, we review the results of the ALSI project (Advanced Laser-writing for Stellar Interferometry), aimed at assessing the potential of ultrafast laser writing to…
