“…Holography is a two or three dimensional (2/3D) imaging technique to record and reconstruct amplitude and phase information from photonic nanostructures by means of diffraction. 1 , 2 High-resolution imaging and multiplexing in holography enable applications in image processing, 3D displays, and security devices. 3 , 4 Additionally, holographic metasurfaces offer broadband readouts at wide-angles, high-efficiency, and arbitrary wavefront shaping.…”

“…The invention of holography goes back to Dennis Gabor, 6 who in 1947 was working on improving the resolution of the recently invented electron microscope (Gabor 1947, Gabor 1948, Gabor et al 1965. In 1971 he was awarded the Nobel Prize in Physics for his invention.…”

Phase retrieval, i.e. the problem of recovering a function from the squared magnitude of its Fourier transform, arises in many applications, such as X-ray crystallography, diffraction imaging, optics, quantum mechanics and astronomy. This problem has confounded engineers, physicists, and mathematicians for many decades. Recently, phase retrieval has seen a resurgence in research activity, ignited by new imaging modalities and novel mathematical concepts. As our scientific experiments produce larger and larger datasets and we aim for faster and faster throughput, it is becoming increasingly important to study the involved numerical algorithms in a systematic and principled manner. Indeed, the past decade has witnessed a surge in the systematic study of computational algorithms for phase retrieval. In this paper we will review these recent advances from a numerical viewpoint.

“…If the object of which a holographic images is to be created is illuminated by an exact (coherent) copy of the reference wave, the transmitted wave is modulated in phase by the intrinsic phase shifting properties of the specimen. When brought to interference, the usual interference pattern appears which carries the full amplitude and phase information of the object, as described and demonstrated for the first time by Gabor [82][83][84] for visible light, but already intended to use this technique as a means to circumvent the limitations imposed by the usual lens aberrations in electron microscopy. Gabor's principle was applied for the first time to electrons by Möllenstedt [85] who managed to record and reconstruct a hologram using electrons of 30 keV energy and an electrostatic biprism as a beam splitter [86].…”

Nanostructured materials become more and more a part of our daily life, partly as self-assembled particles or artificially patterned. These nanostructures often possess intrinsic magnetic and/or electric fields which determine (at least partially) their physical properties. Therefore it is important to be able to measure these fields reliably on a nanometre scale. A rather common instrument for the investigation of these fields is the transmission electron microscope as it offers high spatial resolution. The use of an electron microscope to image electric and magnetic fields on a micron down to sub-nanometre scale is treated in detail for transmission electron microscopes (TEM) and scanning transmission electron microscopes (STEM). The formation of contrast is described for the most common imaging modes, the specific advantages and disadvantages of each technique are discussed and examples are given. In addition, the experimental requirements for the use of the techniques described are listed and explained.
