  We applied the analysis of x-ray intensity angular correlation function to
dilute ensembles of identical spinel crystals. Firstly, we show that the
angular correlation from measured diffraction patterns with many crystals per
shot converges to the correlation for single crystal. Secondly, we determined
the diffraction pattern from single crystal from diffraction patterns of many
crystals. Finally, we discussed the full 3D reciprocal space retrieval and its
potential application in solving structure with dilute powder diffraction data,
where the intensity fluctuation could be observed on each ring.
