The Kossel diffraction technique is well suited for investigating crystal lattices. Progress in digital recording of images opens the opportunity for simplification and improvement of the examination of Kossel patterns. Such patterns can be processed immediately after recording if appropriate computer programs are available. To provide such a tool, a new Windows‐based software for computer‐assisted analysis of Kossel patterns has been developed. With its easy‐to‐operate user interface, the program is intended to facilitate refinement of lattice parameters and determination of elastic strains. The refinement is based on matching experimental and geometrically simulated patterns, whereas the strain is obtained by matching Kossel line profiles in similar experimental patterns. The software is capable of simultaneous handling of multiple patterns.
