Patent ID: 7696991

Claim:
An apparatus for analyzing a twinned crystal comprising: (a) X-ray single crystal structure analytical equipment which can obtain respective crystal orientation matrices of plural components of the twinned crystal with the use of an X-ray diffraction method; (b) first computing means for finding respective real-space unit lattices of the plural components of the twinned crystal based on the crystal orientation matrices and for creating display data for displaying three-dimensionally the real-space unit lattices with an alterable viewpoint on a screen expressing three-dimensional real space; (c) second computing means for finding respective reciprocal-space primitive lattices of the plural components of the twinned crystal based on the crystal orientation matrices and for creating display data for displaying three-dimensionally the reciprocal-space primitive lattices with an alterable viewpoint on a screen expressing three-dimensional reciprocal space; (d) third computing means for finding respective reciprocal lattice points of the plural components of the twinned crystal based on the crystal orientation matrices and for creating display data for displaying three-dimensionally reciprocal lattice points causing X-ray diffraction among the found reciprocal lattice points, with a distinction between the components of the twinned crystal, with an alterable viewpoint on the screen expressing the three-dimensional reciprocal space; and (e) a display for displaying the display data created by the first computing means, the second computing means and the third computing means.
