Small-angle X-ray scattering (SAXS) is a useful technique for nanoscale structural characterization of materials. In SAXS. structural and spatial information is indirectly obtained from the scattering intensity in the spectral domain. known as the reciprocal space. https://www.roneverhart.com/100-Percent-Sunglasses-SPEEDCRAFT-LE-Money-Mike-HiPER-Silver-Mirror/
