Our knowledge of the structure of matter is largely based on X-ray diffraction studies of periodic structures and the successful transformation (inversion) of the diffraction patterns into real-space atomic maps. But the determination of non-periodic nanoscale structures by X-rays is much more difficult. Inversion of the measured diffuse X-ray intensity patterns suffers from the intrinsic loss of phase information, and direct imaging methods are limited in resolution by the available X-ray… 
Advanced Magnetic Nanostructure Characterization via Resonant Soft X-Ray Spectro Holography Imaging in Combination with Microscopic Hysteresis Loop Analysis
In this article the coherence and tunable polarization of soft X-ray synchrotron radiation for imaging magnetic nanostructures via Fourier Transform Holography is discussed. This new lens-less
Magnetic imaging with soft x-ray spectroholography
We present recent advances in imaging magnetic nanostructures via lensless holographic x-ray techniques. In addition to the tunable energy and polarization this method also uses the coherent photon

Advances in the development of free-electron lasers offer the realistic prospect of nanoscale imaging on the timescale of atomic motions. We identify X-ray Fourier-transform holography1,2,3 as a
Dichroic coherent diffractive imaging
TLDR
A novel approach to lensless imaging of an extended magnetic nanostructure is presented, in which a scanned series of dichroic coherent diffraction patterns is recorded and numerically inverted to map its magnetic domain configuration.
Maskless off-axis X-ray Holography
Off-axis X-ray holography is a lensless imaging technique that allows unambiguous retrieval of an object’s exit-wave function with high fidelity. It has been used with great success to study
Holographic and diffractive x-ray imaging using waveguides as quasi-point sources
We report on lensless nanoscale imaging using x-ray waveguides as ultra-small sources for quasi-point-like illumination. We first give a brief account of the basic optical setup, an overview of the
Dynamic Imaging with X-ray Holography
X-ray holography is a type of coherent diffractive imaging where the phase information is physically encoded in the diffraction pattern by means of interference with a reference beam. The image of

X-ray holography is a type of coherent diffractive imaging where the phase information is physically encoded in the diffraction pattern by means of interference with a reference beam. The image of
Ptychographic coherent x-ray diffractive imaging in the water window.
TLDR
An application of ptychographic coherent diffractive imaging (PCDI) in the soft x-ray regime in the so-called water window of photon energies where the high scattering contrast between carbon and oxygen is well-suited to image biological samples is reported.

X-ray holographic microscopy by means of photoresist recording and atomic-force microscope readout
We have reconstructed in-line (or Gabor) x-ray holograms at 40–50-nm resolution from a complex biological specimen. The holograms were recorded as a relief pattern on photoresist with use of 1.89-nm,

The contrast and penetrating power afforded by soft X-rays when they interact with matter makes this form of radiation ideal for studying micrometre-sized objects,. But although soft X-rays areuseful

TLDR

X-ray Linear Dichroism Microscopy
TLDR
The observed dichroism and change in contrast upon rotation arise from the polarization dependence of the near-edge x-ray absorption cross section and can be used to image the orientation of specific chemical bonds.
Potential for biomolecular imaging with femtosecond X-ray pulses
TLDR
Computer simulations are used to investigate the structural information that can be recovered from the scattering of intense femtosecond X-ray pulses by single protein molecules and small assemblies and predict that ultrashort, high-intensity X-rays from free-electron lasers that are currently under development will provide a new approach to structural determinations with X- rays.
Demonstration Of X-Ray Holography With An X-Ray Laser
TLDR
X-ray holography offers the potential for obtaining high resolution three-dimensional images of in vitro biological microstructures and it is proposed to exploit the extremely high brightness and long coherence lengths produced by x-ray lasers and create the hologram with exposure times of less than 1 nsec.
