| Abstract Scope |
In this presentation, I will introduce a framework that is capable of numerically simulating ideal Bragg Coherent Diffraction Imaging (Bragg CDI) experiments. The three-dimensional rocking-curve diffraction data are generated using first-principle forward modeling algorithm that considers crystalline lattice structure, shape function and dislocation field inside an irradiated particle. The simulated data can then be inverted with established phase recovery techniques to deliver real-space images. By systematically investigating the performance of the Bragg CDI method using this framework, the detection limits of dislocation field under various oversampling conditions, noise levels and detection dynamic range are explored. These results have the potential to improve the proper assessment of reconstructed phases from Bragg CDI experiments and to optimize practical guidelines for experimental scenarios. |
