Improved precision and accuracy of electron energy-loss spectroscopy quantification via fine structure fitting with constrained optimization
Daen Jannis, Wouter Van den Broek, Zezhong Zhang +2
By working out the Bethe sum rule, a boundary condition that takes the form of a linear equality is derived for the fine structure observed in ionization edges present in electron…
Convexity constraints on linear background models for electron energy-loss spectra
Wouter Van den Broek, Daen Jannis, Jo Verbeeck
In this paper convexity constraints are derived for a background model of electron energy loss spectra (EELS) that is linear in the fitting parameters. The model outperforms a powe…
Overcoming information reduced data and experimentally uncertain parameters in ptychography with regularized optimization
Marcel Schloz, Thomas C. Pekin, Zhen Chen +3
The overdetermination of the mathematical problem underlying ptychography is reduced by a host of experimentally more desirable settings. Furthermore, reconstruction of the sample-…
Various Compressed Sensing Set-Ups Evaluated Against Shannon Sampling Under Constraint of Constant Illumination
Wouter Van den Broek, Bryan W. Reed, Armand Béché +3
Under the constraint of constant illumination, an information criterion is formulated for the Fisher information that compressed sensing measurements in optical and transmission el…
