ALF: an asymmetric Lyot wavefront sensor for the ELT/METIS vortex coronagraph
Gilles Orban de Xivry, Olivier Absil, Christian Delacroix +3
Non-common path quasi-static and differential aberrations are one of the big hurdles of direct imaging for current and future high-contrast imaging instruments. They increase speck…
A simulator-based autoencoder for focal plane wavefront sensing
Maxime Quesnel, Gilles Orban de Xivry, Olivier Absil +1
Instrumental aberrations strongly limit high-contrast imaging of exoplanets, especially when they produce quasistatic speckles in the science images. With the help of recent advanc…
A deep learning approach for focal-plane wavefront sensing using vortex phase diversity
M. Quesnel, G. Orban de Xivry, G. Louppe +1
The performance of high-contrast imaging instruments is limited by wavefront errors, in particular by non-common path aberrations (NCPAs). Focal-plane wavefront sensing (FPWFS) is…
Focal Plane Wavefront Sensing using Machine Learning: Performance of Convolutional Neural Networks compared to Fundamental Limits
G. Orban de Xivry, M. Quesnel, P. -O. Vanberg +2
Focal plane wavefront sensing (FPWFS) is appealing for several reasons. Notably, it offers high sensitivity and does not suffer from non-common path aberrations (NCPA). The price t…
