Method of and apparatus for producing texture topograms

摘要

A method of and apparatus for producing texture topograms at surface layers of non-amorphous polycrystalline bodies comprises means for producing a divergent beam of monochromatic radiation. The divergent monochromatic radiation beam is diffracted at a polycrystalline body to be examined. Slit-shaped apertures are arranged in the radiation path of the diffracted radiation and extend parallel to the diffraction plane. Means for forming an image of the picture of the diffracted radiation are arranged behind the slit-shaped apertures and at a distance from the surface of the polycrystalline body and the focussed reflex.
