Reciprocal-space mapping

Reciprocal-space mapping (RSM) refers to a suite of scattering methods wherein the three-dimensional reciprocal-space of the sample is reconstructed by iteratively measuring a variety of two-dimensional 'slices' through the space. A given x-ray scattering experiment probes a 2D plane through reciprocal-space (actually a curved surface, known as the Ewald sphere). By reorienting the sample, multiple 'slices' through reciprocal-space can be obtained. These slices can then be combined to yield the full, 3D reciprocal-space.
