Polychromatic pyramid wavefront sensor with MKID technology for high contrast imaging
Aurélie Magniez, Charlotte Z. Bond, Peter Wizinowich +2
The high sensitivity of the pyramid wavefront sensor has made it the preferred sensor in high contrast adaptive optics systems. Future higher contrast systems, like the Extremely L…
Increasing science yield with a twilight observing program with the SCALES instrument at Keck
Isabel J. Kain, Carlos Alvarez, John M. O'Meara +13
While astronomical twilight closes the observing window for optical astronomers, the infrared sky remains dark even through sunrise, allowing IR astronomers to observe through twil…
Technical description and performance of the phase II version of the Keck Planet Imager and Characterizer
Nemanja Jovanovic, Daniel Echeverri, Jacques-Robert Delorme +46
The Keck Planet Imager and Characterizer (KPIC) is a series of upgrades for the Keck II Adaptive Optics (AO) system and the NIRSPEC spectrograph to enable diffraction limited, high…
AI-Powered Low-Order Focal Plane Wavefront Sensing in Infrared
Mojtaba Taheri, Mahdiyar Molahasani, Sam Ragland +2
Adaptive optics (AO) systems are crucial for high-resolution astronomical observations by compensating for atmospheric turbulence. While laser guide stars (LGS) address high-order…
Towards understanding interactions between the AO system and segment co-phasing with the vector-Zernike wavefront sensor on Keck
Maïssa Salama, Charlotte Guthery, Vincent Chambouleyron +14
We extend our previous demonstration of the first on-sky primary mirror segment closed-loop control on Keck using a vector-Zernike wavefront sensor (vZWFS), which improved the Stre…
