  Offering high-brilliance X-ray beams on micrometer length scales, the
microfocus-SAXS at SSRF BL16B1 was established with a KB mirror system for
studying small sample volumes, or probing micro-scopic morphologies. The SAXS
minimum q value was 0.1nm-1 with a flux of 1.5 * 10^10 photons/s. Two
position-resolved scanning experimental methods were combined with
microfocus-SAXS that include STXM and CT. To improve the significant smearing
effect in the horizontal direction, an effective and easy-to-use desmearing
procedure for two-dimensional SAXS pattern based on the blind deconvolution was
developed and the deblurring results demonstrated the good restoration effect
for the defocus image. Finally, a bamboo sample was selected for SAXS-CT
experiment which illustrated the performance of the microfocus-SAXS method.
