Digital processing of growth striation images in a GaSb(Si) single crystal, grown during terrestrial preparation for a space experiment aboard the Foton-M3 space vehicle. (a), (b) Fragments of topographs of region I (10 mm from the recrystallization boundary) and region II (3 mm from the recrystallization boundary), respectively. (c), (d) The corresponding spectrum densities of the intensity distribution, where A is the Fourier amplitude (arbitrary units) and f is the spatial frequency. |
