Figure 1
Scheme of BCDI experiment. A coherent X-ray beam with the incident wavevector ki and exit wavevector kf is scattered by a nanoparticle with a truncated octahedron envelope. The angle between ki and kf is twice the Bragg angle θB of the lattice point G111. The squares across the Bragg peak represent the detector window, whose plane (q1 × q2) is perpendicular to the exit wavevector kf. By rotating the sample in a small range along the rocking curve direction θ, the 3D diffraction volume in reciprocal space can be sampled by a stack of 2D slices recorded by the detector. The q3 direction in reciprocal space corresponds to the rocking curve direction θ. The conjugate space of (q1, q2, q3) is (r1, r2, r3). |
