  Bragg coherent diffraction imaging (BCDI) is a unique and powerful method for
tracking three-dimensional strain fields non-destructively. While BCDI has been
successfully applied to many scientific research fields and receives high
demands, the reconstructed results for highly strained crystals are still
subject to big uncertainties. Here, the progress in improving the suitability
of BCDI for general samples by exploiting wavefront modulation is reported.
Extensive numerical simulations demonstrate that significant improvements over
the current method for reconstructing highly strained model nanocrystals can be
achieved. The proposed method highly suppresses the appearance of ambiguous
solutions and exhibits fast convergence and high robustness in phase retrieval.
Possible experimental difficulties in implementing this method are discussed in
detail.
