Simultaneous estimation of segmented telescope phasing errors and non-common path aberrations from adaptive optics corrected images
Masen Lamb, Carlos Correia, Suresh Sivanandam +2
We investigate the focal plane wavefront sensing technique, known as Phase Diversity, at the scientific focal plane of a segmented mirror telescope with an adaptive optics (AO) sys…
Closed Loop Predictive Control of Adaptive Optics Systems with Convolutional Neural Networks
Robin Swanson, Masen Lamb, Carlos Correia +2
Predictive wavefront control is an important and rapidly developing field of adaptive optics (AO). Through the prediction of future wavefront effects, the inherent AO system servo-…
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…
Focal Plane Wavefront Sensing on SUBARU/SCExAO
Sebastien Vievard, Steven P. Bos, Frederic Cassaing +20
Focal plane wavefront sensing is an elegant solution for wavefront sensing since near-focal images of any source taken by a detector show distortions in the presence of aberrations…
Characterisation of a turbulent module for the MITHIC high-contrast imaging testbed
A. Vigan, M. Postnikova, A. Caillat +6
Future high-contrast imagers on ground-based extremely large telescopes will have to deal with the segmentation of the primary mirrors. Residual phase errors coming from the phase…
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…
