Experimental methods of Bragg coherent diffraction imaging （BCDI） are briefly reviewed. BCDI has become an essential visualization technique that images the 3D displacement and strain field in the crystalline materials in situ. Nevertheless, the BCDI experiment is still not as common as the other conventional X-ray diffraction techniques presumably because of particular instrumentation utilizing delicate coherent X-ray optics and goniometer, which further requires a combination with the data reduction that reconstructs measured particle images during the experiment. Here, we briefly review the experimental methods of BCDI and its application to the alloy nanoparticles. We also discuss the advantages and challenges of BCDI as an analysis method and future perspectives.
