Abstract Scope Bragg Coherent X-ray Diffraction Imaging (BCDI) non-destructively allows for the study of nano-scale defect interactions through the reconstruction of a coherent diffraction pattern. While one Bragg peak provides a projection of the strain along a particular plane normal, it has recently been demonstrated that, by measuring patterns from multiple Bragg reflections and reconstructing them through concurrent phase retrieval, the full strain tensor can be recovered. In the study of bulk polycrystals using high energy BCDI, partial coherence seriously affects the ability to consistently reconstruct Bragg peaks. We propose a new method for strain calculation when peak quality is variable. Using a reconstruction confidence index, Bragg peaks are weighted using least squares weighted fit, giving higher weight to peaks which converge more consistently than others, resulting in more accurate strain tensor recovery.
