ABSTRACT: We
performed a feasibility study of Small angle X-ray scattering imaging under the condition of X-ray bright field
imaging by Laue crystal diffraction optics of X-ray dark-field imaging that
works as an angular analysis. Collagen in chicken tibia containing abundant
soft fibrous tissue was chosen as a specimen. In traditional Small angle X-ray scattering optical system, we can derive the structure
information of sample by calculating q value which is available from a scattering pattern.
Thus it is usually necessary to conduct a 2D scan in order to obtain scattering
image. In this paper it is described by a method by which not only small angle X-ray
scattering imaging is available directly but also bright-field imaging and dark-field imaging can be obtained at the same time. As the first step, the feasibility of the imaging
method should be confirmed by taking pictures of the samples with known
periodic length. The preliminary test showed that the collgan’s lattice spacing d is 65.1 nm that was also taken photos by scanning
electron microscopy. By rotating Laue angular analyzer by 112 arcseconds small angle
X-ray scattering image appeared in bright-field.
