摘要: X-ray refractive lenses are proposed as a Fourier transformer for high-resolution crystal diffraction. By employing the wave transmitted through object converts into spatial intensity distribution at its back focal plane according to Fourier-transform relations. A theoretical consideration of technique is presented. Two types samples were studied in Bragg reflection geometry: grating made strips thin SiO2 film on an Si substrate and by profiling crystal. patterns recorded different angles along rocking curves 111 analysed.
