iMOSFLM: a new graphical interface for diffraction-image processing with MOSFLM
Acta Crystallographica Section D: Biological Crystallography, 2011 A new graphical user interface to the MOSFLM program has been developed to simplify the processing of macromolecular diffraction data. The interface, iMOSFLM, allows data processing via a series of clearly defined tasks and provides visual feedback on ...

Reconfigurable all-dielectric metalens with diffraction-limited performance [PDF]
Nature Communications, 2019 Active metasurfaces, whose optical properties can be modulated post-fabrication, have emerged as an intensively explored field in recent years. The efforts to date, however, still face major performance limitations in tuning range, optical quality, and ...

A comment on the relation between diffraction and entropy [PDF]
, 2012 Diffraction methods are used to detect atomic order in solids. While uniquely ergodic systems with pure point diffraction have zero entropy, the relation between diffraction and entropy is not as straightforward in general.

Lepton-Photon 01, 2002 The most recent theoretical and experimental results in the field of diffractive scattering are reviewed. A parallel between the two current theoretical approaches to diffraction, the DIS picture in the Breit frame and the dipole picture in the target frame, is given, accompanied by a description of the models to which the data are compared.

Analytic expressions and approximations for the on-axis, aberration-free Rayleigh and Debye integral in the case of focusing fields on a circular aperture [PDF]
Journal of the European Optical Society-Rapid Publications, 2008 We present a derivation of the analytic result for on-axis field values of the Rayleigh diffraction integral, a result that was originally presented in a paper by Osterberg and Smith (1961).
