First high-contrast results on THD2 testbed after infrastructure upgrade
Iva Laginja, Pierre Baudoz, Rémi Soummer +17
We present the first scientific results delivered by the upgraded THD2 high-contrast imaging testbed. We report two advances enabled by its improved stability and broadband perform…
Vector Apodizing Phase Plates for the ELT: From prototype to final optics for METIS and MICADO
J. A. van den Born, R. Landman, D. S. Doelman +12
The first generation of instruments for the upcoming Extremely Large Telescope (ELT) will allow for the direct imaging of exoplanets that were previously below the sensitivity or r…
SUPPPPRESS: Prototyping and testing liquid-crystal vector vortex coronagraphs with reduced polarization leakage
Rico Landman, David Doelman, Jeroen Rietjens +16
The vortex coronagraph is one of the most promising candidates for the Habitable Worlds Observatory (HWO) due to its excellent theoretical performance for an off-axis telescope. A…
The VLT/ERIS grating vector Apodizing Phase Plate coronagraph
M. A. Kenworthy, F. A. Dannert, J. Hayoz +29
We describe the design, laboratory manufacture, and on-sky testing of the grating vector apodizing phase plate (gvAPP) coronagraph for the Enhanced Resolution Imager and Spectrogra…
The TOLIMAN mission: A low-cost space telescope for high precision narrow-angle astrometry
Peter Tuthill, Christopher Betters, Max Charles +29
The TOLIMAN project is engaged with the construction, launch and operation of a low-cost space telescope of unorthodox optical design. Its primary science goal targets an exhaustiv…
The Santa Cruz Extreme AO Lab (SEAL) 2.0: A reflective, multi-wavelength rebuild
Rebecca Jensen-Clem, Vincent Chambouleyron, Prince Javier +20
The Santa cruz Extreme Adaptive optics Lab (SEAL) is a visible/near-infrared wavelength testbed designed to support technology development for high contrast imaging on large, segme…
VSTPOL: making the VST a large survey telescope for optical polarimetry
P. Schipani, S. Covino, F. Snik +30
Since the start of operations in 2011, the VLT Survey Telescope (VST) has been one of the most efficient wide-field imagers in the optical bands. However, in the next years the Ver…
Prototyping liquid-crystal coronagraphs for exo-Earth imaging
Iva Laginja, David Doelman, Frans Snik +12
This paper presents initial results from the ESA-funded ``SUPPPPRESS'' project, which aims to develop high-performance liquid-crystal coronagraphs for direct imaging of Earth-like…
METIS high-contrast imaging: from final design to manufacturing and testing
Olivier Absil, Matthew Kenworthy, Christian Delacroix +21
The Mid-infrared ELT Imager and Spectrograph (METIS) is one of the first-generation scientific instruments for the ELT, built under the supervision of ESO by a consortium of resear…
Sub-percent Characterization and Polarimetric Performance Analysis of Commercial Micro-polarizer Array Detectors
Thijs Stockmans, Naor Scheinowitz, Erwoud van der Linden +4
Polarization imaging can yield crucial information in multiple applications of remote sensing, such as characterization of clouds, aerosols, and the Aurora Borealis. Some applicati…
First on-sky demonstration of spatial Linear Dark Field Control with the vector-Apodizing Phase Plate at Subaru/SCExAO
S. P. Bos, K. L. Miller, J. Lozi +9
One of the key noise sources that currently limits high-contrast imaging observations for exoplanet detection is quasi-static speckles. Quasi-static speckles originate from slowly…
ERIS: revitalising an adaptive optics instrument for the VLT
Richard Davies, Simone Esposito, Hans Martin Schmid +63
ERIS is an instrument that will both extend and enhance the fundamental diffraction limited imaging and spectroscopy capability for the VLT. It will replace two instruments that ar…
