Damage Identification Method of Beam Structure Based on Modal Curvature Utility Information Entropy

, 2020
Generally, the damage of the structure will lead to the discontinuity of the local mode shape, which can be well reflected by the modal curvature of the structure, and the local information entropy of the beam structure will also change with the ...

Profiling structured beams using injected aerosols [PDF]

SPIE Proceedings, 2012
Profiling structured beams produced by X-ray free-electron lasers (FELs) is crucial to both maximizing signal intensity for weakly scattering targets and interpreting their scattering patterns. Earlier ablative imprint studies describe how to infer the X-ray beam profile from the damage that an attenuated beam inflicts on a substrate.
