Abstract Scope Coherent x-ray diffraction imaging (CDI) performed in Bragg geometry has been employed as a powerful technique to examine three-dimensional strain distributions within nanocrystals. However the current state-of-art of CDI requires significant time to perform three-dimensional scans making it incompatible with most time-resolved studies. In this talk, I will discuss a new approach for CDI with the goal of obtaining three-dimensional coherent x-ray diffraction patterns without scanning samples. Polychromatic coherent x-ray delivered by third-generation synchrotron sources allows transient diffraction patterns collected during phase transition of the sample within short time. It also makes CDI on complex heterogeneous crystalline materials simplified with a two stage, screening and imaging process. This innovative approach may provide opportunities for time-resolved Bragg CDI studies.
