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.
The diffraction pattern of X rays fired through the material provided information about the arrangements of atoms in the silica.
The enhanced Green Card design beginning with this order will add new security technology, including the incorporation of Drexler's high security optically variable device (OVD) diffraction pattern into the card's optical media.
