To produce MOIRE's optical-quality polymer membranes and the precision etching needed to generate the diffraction pattern, Ball worked with NeXolve and the Lawrence Livermore National Laboratory.
In either case, the diffraction pattern due to the principal aperture A can be evaluated using a generalized Fresnel integral derived by this author from the general equations for the propagation of cross-spectral density in a partially coherent optical field (3).
He predicted that the crystal would scatter the x-rays in different directions with different intensities, and that the nature of this so-called diffraction pattern would be uniquely determined by the structure of the crystal, meaning the arrangement of the atoms in the crystal.
An X-ray diffraction (XRD) system transmits X-ray beams to a sample (generally a single crystal, metallic solid or a powder) and records the diffraction pattern that occurs when the X-ray photons encounter the inter-atomic gaps within the crystal structure.
