X-ray refractive lenses are proposed as a Fourier transformer for\nhigh-resolution X-ray crystal diffraction. By employing refractive\nlenses the wave transmitted through the object converts into a spatial\nintensity distribution at its back focal plane according to the\nFourier-transform relations. A theoretical consideration of the\nFourier-transform technique is presented. Two types of samples were\nstudied in Bragg reflection geometry: a grating made of strips of a thin\nSiO2 film on an Si substrate and a grating made by profiling an Si\ncrystal. Fourier patterns recorded at different angles along the rocking\ncurves of the Si 111 Bragg reflection were analysed.
