Local Turbulence: Effects and causes
Olivier Lai, Kanoa Withington, Romain Laugier +1
Dome seeing is a known source of image quality degradation, but despite tremendous progress in wavefront control with the development of adaptive optics and environmental control t…
The Keck Planet Imager and Characterizer: Demonstrating advanced exoplanet characterization techniques for future extremely large telescopes
N. Jovanovic, J. R. Delorme, C. Z. Bond +25
The Keck Planet Imager and Characterizer (KPIC) is an upgrade to the Keck II adaptive optics system enabling high contrast imaging and high-resolution spectroscopic characterizatio…
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…
Entering into the Wide Field Adaptive Optics Era on Maunakea
Gaetano Sivo, John Blakeslee, Jennifer Lotz +32
As part of the National Science Foundation funded "Gemini in the Era of MultiMessenger Astronomy" (GEMMA) program, Gemini Observatory is developing GNAO, a widefield adaptive optic…
Visible and Near Infrared Laboratory Demonstration of a Simplified Pyramid Wavefront Sensor
Julien Lozi, Nemanja Jovanovic, Olivier Guyon +4
Wavefront sensing and control are important for enabling one of the key advantages of using large apertures, namely higher angular resolutions. Pyramid wavefront sensors are becomi…
