摘要

1. A method for investigating the structure of photonic crystals and other spatially ordered mesoscopic materials using the three-dimensional reconstruction of the reciprocal space, characterized in that the mathematical processing performed diffraction patterns set for isolating background signal component constituting the scattering by individual elements of structure and the diffraction grating element in an orderly .2. A method according to claim 1, characterized in that it can be implemented in the methods of X-ray, electron and neutron diffraction and diffraction scattering experiments of other electromagnetic izlucheniya.3. A method according to claim 1, characterized in that the reconstitution of the complete crystals reciprocal space takes place according to the diffraction patterns obtained when the sample is rotated 180 ° .4. A method according to claim 3, characterized in that the reflections analyzed to identify dependency, where q - rasseyaniya.5 vector. A method according to claim 4, characterized in that the series of processing allows the diffraction image, to form one single field data representing a three-dimensional reconstruction of the reciprocal space, and to hold it postprocessing for the quantification of intensivnosti.6 distribution. A method according to claim 4, characterized in that the background for the description of the function is used a regression analysis method; in the small angle region for describing background function uses power function I (q) = kg + I, a wide angle - exponential function I (q) = exp (k-ng) + I, where g - scattering vector, k, and n - constants dependent contrast and shape of scattering particles, I- detektora.7 dark signal. A method according to claim 7, wherein
