- A Fourier approach to fields and electron optical phase-shifts calculationsM Beleggia
Materials Science Department, Brookhaven National Laboratory, Upton, NY 11973, USA
Ultramicroscopy 96:93-103. 2003..It is shown that this approach not only allows to take into account rather easily the effect of the fringing fields protruding in the space around the specimen, but also to obtain solutions to interesting models in analytical form...
- On the transport of intensity technique for phase retrievalM Beleggia
Brookhaven National Laboratory, Center for Functional Nanomaterials, Building 480, Upton, NY 11973, USA
Ultramicroscopy 102:37-49. 2004..Another example is given, the reconstruction of a phase jump, accompanied with experimental support showing that phase retrieval by Electron Holography and Transport of Intensity techniques yields results in good agreement...
- Characterization of JEOL 2100F Lorentz-TEM for low-magnification electron holography and magnetic imagingM A Schofield
Brookhaven National Laboratory, Condensed Matter, Physics and Materials Science Department, Building 480, Upton, NY 11973, USA
Ultramicroscopy 108:625-34. 2008..These results indicate the usefulness of measuring these optical parameters to guide the optimization of the experimental setup for a given microscope, and to provide an additional degree of practical experimental possibility...
