On joint eigen-decomposition of matrices

Autor: Troedsson, Erik, Falkowski, Daniel, Lidgren, Carl-Fredrik, Wendt, Herwig, Carlsson, Marcus

The problem of approximate joint diagonalization of a collection of matrices arises in a number of diverse engineering and signal processing problems. This problem is usually cast as an optimization problem, and it is the main goal of this publicatio

Single-distance nano-holotomography with coded apertures

Autor: Nikitin, Viktor, Carlsson, Marcus, Mokso, Rajmund, Cloetens, Peter, Gursoy, Doga

High-resolution phase-contrast 3D imaging using nano-holotomography typically requires collecting multiple tomograms at varying sample-to-detector distances, usually 3 to 4. This multi-distance approach significantly limits temporal resolution, makin

X-ray nano-holotomography reconstruction with simultaneous probe retrieval

Autor: Nikitin, Viktor, Carlsson, Marcus, Gursoy, Doga, Mokso, Rajmund, Cloetens, Peter

In conventional tomographic reconstruction, the pre-processing step includes flat-field correction, where each sample projection on the detector is divided by a reference image taken without the sample. When using coherent X-rays as probe, this appro
