    Abstract: A method of imaging phases in an inhomogeneous polycrystalline sample having a plurality of crystallites of at least a first crystalline component includes illuminating an illuminated area extending across a surface of a sample with substantially monochromatic X-rays incident at a Bragg-Brentano parafocussing geometry at first angle θ1 to the surface of the sample. X-rays diffracted by the sample at a second angle θ2 pass through a pinhole. The diffraction angle θ1+θ2 fulfils a Bragg condition for the first crystalline component which is imaged by a detector to provide a two-dimensional image of the first crystalline component at the surface of the sample.
