(a) Side view of the setup for micro-small-angle scattering tomography. (b) Top view of the sample region.
(Color online) Small-angle x-ray scattering patterns of an injection-molded polyethylene rod (cylinder axis parallel to ) recorded with an x-ray microbeam impinging (a) peripherally and (b) centrally. The intensity scale is logarithmic.
Reconstructed attenuation coefficient and integral scattered intensity along the axis as a function of and on a virtual section through the sample. The diffraction patterns reconstructed at the locations marked in the right image are shown in Fig. 4.
(Color online) Reconstructed SAXS cross section along the direction [, left] and 2D sections through reciprocal space [, right] at different locations in the tomographic reconstruction shown in Fig. 3. The arrows indicate the period of the lamellar structure.
