SHIMM as an atmospheric profiler on the Nickel Telescope
Ollie Jackson, Maaike A. M. van Kooten, Saavidra Perera +2
Optimal atmospheric conditions are beneficial for detecting exoplanets via high contrast imaging (HCI), as speckles from adaptive optics' (AO's) residuals can make it difficult to…
Using the Gerchberg-Saxton algorithm to reconstruct non-modulated pyramid wavefront sensor measurements
Vincent Chambouleyron, Aditya Sengupta, Maïssa Salama +9
Adaptive optics (AO) is a technique to improve the resolution of ground-based telescopes by correcting, in real-time, optical aberrations due to atmospheric turbulence and the tele…
Daytime calibration and testing of the Keck All sky Precision Adaptive Optics Tomography System
Avinash Surendran, Jacques R. Delorme, Carlos M. Correia +12
The development of the Keck All sky Precision Adaptive optics (KAPA) project was initiated in September 2018 to upgrade the Keck I adaptive optics (AO) system to enable laser tomog…
Developing Adaptive Secondary Mirror Concepts for the APF and W.M. Keck Observatory Based on HVR Technology
Philip M. Hinz, Rachel Bowens-Rubin, Christoph Baranec +16
An Adaptive secondary mirror (ASM) allows for the integration of adaptive optics (AO) into the telescope itself. Adaptive secondary mirrors, based on hybrid variable reluctance (HV…
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…
Design and development of a high-speed Visible Pyramid Wavefront Sensor for the MMT AO system
Narsireddy Anugu, Olivier Durney, Katie M. Morzinski +16
MAPS, MMT Adaptive optics exoPlanet characterization System, is the upgrade of legacy 6.5m MMT adaptive optics system. It is an NSF MSIP-funded project that includes (i) refurbishi…
Performance of Large-Format Deformable Mirrors Constructed with TNO Variable Reluctance Actuators
Rachel Bowens-Rubin, Philip Hinz, Wouter Jonker +3
Advancements in making high-efficiency actuators are an enabling technology for building the next generation of large-format deformable mirrors. The Netherlands Organization for Ap…
High Performance Lyot and PIAA Coronagraphy for Arbitrarily shaped Telescope Apertures
Olivier Guyon, Philip H. Hinz, Eric Cady +2
Two high performance coronagraphic approaches compatible with segmented and obstructed telescope pupils are described. Both concepts use entrance pupil amplitude apodization and a…
