Continuous Diffraction of Molecules and Disordered Molecular Crystals
Henry N. Chapman, Oleksandr M. Yefanov, Kartik Ayyer +6
The diffraction pattern of a single non-periodic compact object, such as a molecule, is continuous and is proportional to the square modulus of the Fourier transform of that object…
Cryptotomography: reconstructing 3D Fourier intensities from randomly oriented single-shot diffraction patterns
N. D. Loh, M. Bogan, V. Elser +17
We reconstructed the 3D Fourier intensity distribution of mono-disperse prolate nano-particles using single-shot 2D coherent diffraction patterns collected at DESY's FLASH facility…
Ultrafast, ultrabright, X-ray holography using a uniformly-redundant array
S. Marchesini, S. Boutet, A. E. Sakdinawat +15
Advances in the development of free-electron lasers offer the realistic prospect of high-resolution imaging to study the nanoworld on the time-scale of atomic motions. We identify…
Femtosecond Diffractive Imaging with a Soft-X-ray Free-Electron Laser
Henry N. Chapman, Anton Barty, Michael J. Bogan +31
Theory predicts that with an ultrashort and extremely bright coherent X-ray pulse, a single diffraction pattern may be recorded from a large macromolecule, a virus, or a cell befor…
Phase Aberrations in Diffraction Microscopy
S. Marchesini, H. N. Chapman, A. Barty +5
In coherent X-ray diffraction microscopy the diffraction pattern generated by a sample illuminated with coherent x-rays is recorded, and a computer algorithm recovers the unmeasure…
Progress in Three-Dimensional Coherent X-Ray Diffraction Imaging
S. Marchesini, H. N. Chapman, A. Barty +14
The Fourier inversion of phased coherent diffraction patterns offers images without the resolution and depth-of-focus limitations of lens-based tomographic systems. We report on ou…
High-resolution ab initio three-dimensional X-ray diffraction microscopy
H. N. Chapman, A. Barty, S. Marchesini +10
Coherent X-ray diffraction microscopy is a method of imaging non-periodic isolated objects at resolutions only limited, in principle, by the largest scattering angles recorded. We…
