title = "Four-dimensional pink-beam x-ray phase tomography for studying laser processing",
abstract = "X-ray phase tomography by Talbot interferometry functions with X-rays of a broad energy band, and a pink- beam extracted by a multilayer mirror from white synchrotron radiation is used for four-dimensional X-ray phase tomography, which was developed at BL28B2, SPring-8, Japan. Polymer samples under infrared laser irradiation were observed as model experiments of laser processing. In this paper, laser ablation for a carbon-fiber reinforced polymer (CFRP) sample is reported. Thanks to the fact that the fibrous structure generates visibility (or dark-field) contrast, four-dimensional tomogram from the visibility reduction is presented. A technical effort to improve the temporal resolution from 1 s to 160 ms is also described.",
