Ground control to major time-lag: on-sky results of data-driven predictive wavefront control at Keck Observatory
Jules Fowler, Rebeca Jensen-Clem, Sylvain Cetre +12
Directly imaging and characterizing exoplanets requires extreme adaptive optics (XAO), which achieves exquisite wavefront correction over a small (<5") field of view. Temporal erro…
Slow focus sensor for the Keck I laser guide star adaptive optics system using focal plane wavefront sensing
Rafael M. Salgueiro, Carlos M. Correia, Benoit Neichel +7
Laser guide stars (LGSs) have been deployed for the last 20-30 years in ground-based astronomical telescopes to overcome the limited sky coverage of classical adaptive optics (AO)…
Geometric Distortion Calibration with Photo-lithographic Pinhole Masks for High-Precision Astrometry
Maxwell Service, Jessica R. Lu, Mark Chun +5
Adaptive optics (AO) systems deliver high-resolution images that may be ideal for precisely measuring positions of stars (i.e. astrometry) if the system has stable and well-calibra…
Improved Image Quality Over 10' Fields with the `Imaka Ground Layer Adaptive Optics Experiment
Fatima Abdurrahman, Jessica R. Lu, Mark Chun +5
`Imaka is a ground layer adaptive optics (GLAO) demonstrator on the University of Hawaii 2.2m telescope with a 24'x18' field-of-view, nearly an order of magnitude larger than previ…
