Extension of Friedel's law to Vortex Beam Diffraction
Roeland Juchtmans, Giulio Guzzinati, Jo Verbeeck
Friedel's law states that the modulus of the Fourier transform of real functions is centrosymmetric, while the phase is antisymmetric. As a consequence of this, elastic scattering…
Investigation into spiral phase plate contrast in optical and electron microscopy
Roeland Juchtmans, Laura Clark, Axel Lubk +1
The use of phase plates in the back focal plane of a microscope is a well established technique in optical microscopy to increase the contrast of weakly interacting samples and is…
Local orbital angular momentum revealed by spiral phase plate imaging in transmission electron microscopy
Roeland Juchtmans, Jo Verbeeck
The orbital angular momentum (OAM) of light and matter waves is a parameter that is getting increasingly more attention over the past couple of years. Beams with a well defined OAM…
Shaping electron beams for the generation of innovative measurements in the (S)TEM
Jo Verbeeck, Giulio Guzzinati, Laura Clark +6
In TEM, a typical goal consists of making a small electron probe in the sample plane in order to obtain high spatial resolution in scanning transmission electron microscopy. In ord…
