High contrast imaging wavefront sensor referencing from coronagraphic images
Nour Skaf, Olivier Guyon, Anthony Boccaletti +11
A key challenge of high contrast imaging (HCI) is to differentiate a speckle from an exoplanet signal. The sources of speckles are a combination of atmospheric residuals and aberra…
On-sky validation of image-based adaptive optics wavefront sensor referencing
Nour Skaf, Olivier Guyon, Eric Gendron +14
Differentiating between an exoplanet signal and residual speckle noise is a key challenge in high-contrast imaging. Speckles are due to a combination of fast, slow and static wavef…
High contrast imaging at the photon noise limit with self-calibrating WFS/C systems
Olivier Guyon, Barnaby Norris, Marc-Antoine Martinod +20
High contrast imaging (HCI) systems rely on active wavefront control (WFC) to deliver deep raw contrast in the focal plane, and on calibration techniques to further enhance contras…
SCExAO, a testbed for developing high-contrast imaging technologies for ELTs
Kyohoon Ahn, Olivier Guyon, Julien Lozi +21
To directly detect exoplanets and protoplanetary disks, the development of high accuracy wavefront sensing and control (WFS&C) technologies is essential, especially for ground-base…
Learning the Lantern: Neural network applications to broadband photonic lantern modelling
David Sweeney, Barnaby R. M. Norris, Peter Tuthill +4
Photonic lanterns allow the decomposition of highly multimodal light into a simplified modal basis such as single-moded and/or few-moded. They are increasingly finding uses in astr…
Full characterization of the instrumental polarization effects of the spectropolarimetric mode of SCExAO-CHARIS
G. J. Joost `t Hart, Rob G. van Holstein, Steven P. Bos +19
SCExAO at the Subaru telescope is a visible and near-infrared high-contrast imaging instrument employing extreme adaptive optics and coronagraphy. The instrument feeds the near-inf…
