Suppressing dynamical diffraction artefacts in differential phase contrast scanning transmission electron microscopy of long-range electromagnetic fields via precession
T. Mawson, A. Nakamura, T. C. Petersen +5
In differential phase contrast scanning transmission electron microscopy (DPC-STEM), variability in dynamical diffraction resulting from changes in sample thickness and local cryst…
Aberrations in shift-invariant linear optical imaging systems using partially coherent fields
Mario A. Beltran, Marcus J. Kitchen, T. Petersen +1
Here the role and influence of aberrations in optical imaging systems employing partially coherent complex scalar fields is studied. Imaging systems require aberrations to yield co…
Bloch Sphere Catastrophes
Samuel A. Eastwood, David M. Paganin, Timothy C. Petersen +1
Caustics are optical phenomena which occur when a family of rays creates an envelope of divergent intensity. Here we show that caustic surfaces also appear when a real or complex f…
