New phase-retrieval methods to directly invert Bragg coherent diffraction imaging data on an orthogonal grid under even and uneven signal sampling conditions are described.

This article provides a unifying description of the diffraction and signal acquisition geometries of a 3D Bragg coherent diffraction imaging (BCDI) measurement, obtained from fundamental considerations of Fourier-conjugate spaces. Rigorously derived and presented in a compact operator notation, this approach can be easily generalized to any set of BCDI degrees of freedom.

The commissioning of a movable X-ray monochromator at the 34-ID-C endstation of the Advanced Photon Source is reported. The new instrument allows indexing of nanocrystals with Laue diffraction and collecting multi-reflection BCDI data.

A workflow for orienting and mapping nanocrystals on a substrate of a different material lattice using scanning Laue diffraction microscopy has been established.
