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…

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…
