Improvements on speed, stability and field of view in adaptive optics OCT for anterior retinal imaging using a pyramid wavefront sensor Open
We present improvements on the adaptive optics (AO) correction method using a pyramid wavefront sensor (P-WFS) and introduce a novel approach for closed-loop focus shifting in retinal imaging. The method’s efficacy is validated through in …

The MICADO first light imager for the ELT: overview and current status Open
The highest scientific return, for adaptive optics (AO) observations, is\nachieved with a reliable reconstruction of the PSF. This is especially true for\nMICADO@ELT. In this presentation, we will focus on extending the MICADO PSF\nreconst…

The MICADO first light imager for the ELT: the PSF Reconstruction Software Open
MICADO is the first-light camera of the ESO ELT, allowing NIR imaging and long-slit spectroscopy assisted by adaptive optics. MICADO is now entering its construction phase, and the software for data reduction is reaching an adequate maturi…

Matrix-free vs. matrix-based real-time control for a MORFEO-like setting Open
The Multiconjugate adaptive Optics Relay For ELT Observations (MORFEO) is one of the key Adaptive Optics (AO) systems on the ELT, aiming for a good wavefront correction over a large field of view. To compensate for the rapidly changing atm…

Status of the PSF Reconstruction Work Package for MICADO ELT Open
MICADO is a workhorse instrument for the ESO ELT, allowing first light capability for diffraction limited imaging and long-slit spectroscopy at near-infrared wavelengths. The PSF Reconstruction (PSF-R) Team of MICADO is currently implement…

Matrix-free Monolithic Multigrid Methods for Stokes and Generalized Stokes Problems Open
We consider the widely used continuous $\mathcal{Q}_{k}$-$\mathcal{Q}_{k-1}$ quadrilateral or hexahedral Taylor-Hood elements for the finite element discretization of the Stokes and generalized Stokes systems in two and three spatial dimen…

Parallel Matrix-Free Higher-Order Finite Element Solvers for Phase-Field Fracture Problems Open
Phase-field fracture models lead to variational problems that can be written as a coupled variational equality and inequality system. Numerically, such problems can be treated with Galerkin finite elements and primal-dual active set method…

Parallel Block-Preconditioned Monolithic Solvers for Fluid-Structure-Interaction Problems Open
In this work, we consider the solution of fluid-structure interaction problems using a monolithic approach for the coupling between fluid and solid subproblems. The coupling of both equations is realized by means of the arbitrary Lagrangia…
