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…
The vector-apodizing phase plate coronagraph: design, current performance, and future development
D. S. Doelman, F. Snik, E. H. Por +50
Over the last decade, the vector-apodizing phase plate (vAPP) coronagraph has been developed from concept to on-sky application in many high-contrast imaging systems on 8-m class t…
The Automated Data Extraction, Processing, and Tracking System for CHARIS
Taylor L. Tobin, Jeffery Chilcote, Timothy Brandt +4
CHARIS is an IFS designed for imaging and spectroscopy of disks and sub-stellar companions. To improve ease of use and efficiency of science production, we present progress on a fu…
On-sky performance and recent results from the Subaru coronagraphic extreme adaptive optics system
Thayne Currie, Olivier Guyon, Julien Lozi +10
We describe the current on-sky performance of the Subaru Coronagraphic Extreme Adaptive Optics (SCExAO) instrument on the Subaru telescope on Maunakea, Hawaii. SCExAO is continuing…
