The power spectrum extended technique applied to images of binary stars in the infrared

no code implementations17 Dec 2020 Eric Aristidi, Eric Cottalorda, Marcel Carbillet, Lyu Abe, Karim Makki, Jean-Pierre Rivet, David Vernet, Philippe Bendjoya

We recently proposed a new lucky imaging technique, the Power Spectrum Extended (PSE), adapted for image reconstruction of short-exposure astronomical images in case of weak turbulence or partial adaptive optics correction.

Estimating low-order aberrations through a Lyot coronagraph with a Zernike wavefront sensor for exoplanet imaging

no code implementations15 Dec 2020 Raphaël Pourcelot, Mamadou N'Diaye, Greg Brady, Marcel Carbillet, Kjetil Dohlen, Julia Fowler, Iva Laginja, Matthew Maclay, James Noss, Marshall Perrin, Pete Petrone, Emiel Por, Jean-François Sauvage, Rémi Soummer, Arthur Vigan, Scott Will

To calibrate these pointing errors and other critical low-order aberrations, we propose a wavefront sensing path based on Zernike phase-contrast methods to analyze the starlight that is filtered out by the coronagraph at the telescope focus.

DO-CRIME: Dynamic On-sky Covariance Random Interaction Matrix Evaluation, a novel method for calibrating adaptive optics systems

no code implementations30 Nov 2020 Olivier Lai, Mark Chun, Ryan Dungee, Jessica Lu, Marcel Carbillet

This calibration usually takes the form of an interaction matrix and is a measure of the response on the wavefront sensor to wavefront corrector stimulus.
