Predictive wavefront control on Keck II adaptive optics bench: on-sky coronagraphic results
Maaike A. M. van Kooten, Rebecca Jensen-Clem Sylvain Cetre, Sam Ragland +3
The behavior of an adaptive optics (AO) system for ground-based high contrast imaging (HCI) dictates the achievable contrast of the instrument. In conditions where the coherence ti…
The Santa Cruz Extreme AO Lab (SEAL): Design and First Light
Rebecca Jensen-Clem, Daren Dillon, Benjamin Gerard +9
The Santa Cruz Extreme AO Lab (SEAL) is a new visible-wavelength testbed designed to advance the state of the art in wavefront control for high contrast imaging on large, segmented…
First Experimental Results of the Fast Atmospheric Self-coherent Camera Technique on the Santa cruz Extreme Adaptive optics Laboratory Testbed: Demonstration of High Speed Focal Plane Wavefront Control of Residual Atmospheric Speckles
Benjamin L. Gerard, Daren Dillon, Sylvain Cetre +3
Current and future high contrast imaging instruments aim to detect exoplanets at closer orbital separations, lower masses, and/or older ages than their predecessors, with the event…
Status of predictive wavefront control on Keck II adaptive optics bench: on-sky coronagraphic results
Maaike A. M. van Kooten, Rebecca Jensen-Clem, Sylvain Cetre +4
The behavior of an adaptive optics (AO) system for ground-based high contrast imaging (HCI) dictates the achievable contrast of the instrument. In conditions where the coherence ti…
Demonstrating predictive wavefront control with the Keck II near-infrared pyramid wavefront sensor
Rebecca Jensen-Clem, Charlotte Z. Bond, Sylvain Cetre +5
The success of ground-based instruments for high contrast exoplanet imaging depends on the degree to which adaptive optics (AO) systems can mitigate atmospheric turbulence. While m…
