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…
Phase Retrieval and Design with Automatic Differentiation
Alison Wong, Benjamin Pope, Louis Desdoigts +3
The principal limitation in many areas of astronomy, especially for directly imaging exoplanets, arises from instability in the point spread function (PSF) delivered by the telesco…
An all-photonic focal-plane wavefront sensor
Barnaby R. M. Norris, Jin Wei, Christopher H. Betters +2
Adaptive optics (AO) is critical in astronomy, optical communications and remote sensing to deal with the rapid blurring caused by the Earth's turbulent atmosphere. But current AO…
Overview of focal plane wavefront sensors to correct for the Low Wind Effect on SUBARU/SCExAO
Sebastien Vievard, Steven Bos, Frederic Cassaing +15
The Low Wind Effect (LWE) refers to a phenomenon that occurs when the wind speed inside a telescope dome drops below m/s creating a temperature gradient near the telescope spide…
