Testing of machine learning wavefront sensing algorithms on the Tiny Observatory for Telescope Optimization (TOTO) testbed
Sanchit Sabhlok, Solvay A. Blomquist, Maggie Y +16
Phase retrieval techniques are utilized to correct low order wavefront aberrations originating from misalignments of the optical system in space based telescope concepts. Tradition…
Tiny Observatory for Telescope Optimization (TOTO): testing algorithms for autonomous on-orbit alignment for space-based telescope systems
Solvay A. Blomquist, Sanchit Sabhlok, Hyukmo Kang +11
The Tiny Observatory for Telescope Optimization (TOTO) is an optical testbed designed to evaluate the efficacy of autonomously driven alignment algorithms for space-based telescope…
Cascade adaptive optics with a second stage based on a Zernike wavefront sensor for exoplanet observations II. Validation in broadband light on the ESO/GHOST testbed
A. Rahim, M. N'Diaye, A. Vigan +10
Current high-contrast facilities on the ground use extreme adaptive optics (XAO) systems to achieve contrasts down to at 200\,mas for exoplanet observations. This perform…
