abstract = {The mapping of static electric and magnetic fields using
electron probes with a resolution and sensitivity that are
sufficient to reveal nanoscale features in materials
requires the use of phase-sensitive methods such as the
shadow technique, coherent Foucault imaging and the
Transport of Intensity Equation. Among these approaches,
image-plane off-axis electron holography in the transmission
electron microscope has acquired a prominent role thanks to
its quantitative capabilities and broad range of
applicability. After a brief overview of the main ideas and
methods behind field mapping, we focus on theoretical models
that form the basis of the quantitative interpretation of
electron holographic data. We review the application of
electron holography to a variety of samples (including
electric fields associated with p–n junctions in
semiconductors, quantized magnetic flux in superconductors
and magnetization topographies in nanoparticles and other
magnetic materials) and electron-optical geometries
(including multiple biprism, amplitude and mixed-type
set-ups). We conclude by highlighting the emerging
perspectives of (i) three-dimensional field mapping using
electron holographic tomography and (ii) the
model-independent determination of the locations and
magnitudes of field sources (electric charges and magnetic
dipoles) directly from electron holographic data.},
