Refractive optics is proposed as a Fourier transformer for high\nresolution X-ray crystal diffraction. Employing refractive lenses the\nwave transmitted through the object transforms into spatial intensity\ndistribution at its back focal plane according to the Fourier relations.\nA theoretical consideration of the Fourier transform technique is\npresented. Two types of samples were studied in Bragg reflection\ngeometry: a grating made of strips of a thin SiO2 film on Si substrate\nand a grating made by profiling a Si crystal. Rocking curves of Si(111)\nBragg reflection and corresponding Fourier patterns were analyzed. © (2013) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE).
