X光同調散射影像術

X-ray Coherent Diffraction Imaging

摘要


X光同調散射顯微術,是近十年快速發展的X光顯微技術。相較於過往的X光顯微術,同調散射顯微術最大的優勢在於其成像解析度並不受限於X光光學元件的品質,其解析度普遍可優於10奈米。此外,X光同調散射顯微術,可以結合既有的成熟X光實驗技術,如X光吸收光譜或X光單晶繞射,便可同時獲取高解析度影像及其他X光技術資訊,例如元素定位或晶體內的應力場分析。

並列摘要


X-ray coherent diffraction imaging is a rapidly advancing X-ray microscopy technique of the past decade. In contrast to conventional X-ray microscopy, the foremost advantage of coherent scattering imaging lies in its spatial imaging resolution not being constrained by the quality of X-ray optical components. Its resolution can generally surpass 10 nanometers. Furthermore, X-ray coherent scattering imaging has the capability to integrate mature X-ray experimental techniques, such as X-ray absorption spectroscopy or X-ray single crystal diffraction. This integration can generate high-resolution images that retain the information from these existing techniques, such as element mappings on samples or strain analyzing in crystals.
