Elastic and plastic strain measurement in high temperature environment using laser speckle [PDF]
Two laser speckle methods are described to measure strain in high temperature environment and thermal strain caused by high temperature. Both are non-contact, non-destructive and remote sensing techniques that can be automated. The methods have different

X‐ray waveguide optics at GINIX/P10 PETRA III: recent progress and future directions
Journal of Synchrotron Radiation, Volume 33, Issue 2, Page 298-313, March 2026.X‐ray waveguide optics enable spatial and coherence filtering of a nano‐focused synchrotron beam and provide tailored illumination wavefronts for holographic imaging. Progress in fabrication, characterization and advanced waveguide interferometers can enhance holographic imaging.Here we report on recent progress in X‐ray waveguide optics for full‐field

Optical strain measuring techniques for high temperature tensile testing [PDF]
A number of optical techniques used for the analysis of in-plane displacements or strains are reviewed. The application would be for the high temperature, approximately 1430 C (2600 F), tensile testing of ceramic composites in an oxidizing atmosphere ...

Topological transformations of speckles
, 2019 Deterministic control of coherent random light is highly important for information transmission through complex media. However, only a few simple speckle transformations can be achieved through diffusers without prior characterization. As recently shown,

Comparing image quality of synchrotron and laboratory nano‐CT scans: a round robin study
Journal of Synchrotron Radiation, Volume 33, Issue 2, Page 489-507, March 2026.A multi‐facility round‐robin comparison of synchrotron‐ and laboratory‐based nano‐computed tomography using a standardized 3D phantom reveals superior resolution and acquisition speed at synchrotrons, while advanced laboratory systems achieve competitive image quality with extended scan times; phase contrast modalities further enhance structural ...
