VEC

VEC Image processing in HREM and ab initio determination of incommensurate structure from electron and X-ray diffraction data

  • Operating systems: Windows95, 98, NT, 2000 and XP
  • VEC is a program for Visual computing in Electron Crystallography with the following features:
    • Preliminary processing of electron microscopy images
    • Indexing and extracting intensities of electron diffraction patterns
    • Searching defocus value from a single electron microscopy image
    • Resolution enhancement of electron microscopy images using direct methods
    • Simulation of dynamical/kinematical electron diffraction patterns and electron microscopy images for conventional and modulated crystals
    • 2-, 3- and 4-dimensional FFT
    • 2-dimensional half-tone-graph display of 2-, 3- and 4-dimensional Fourier maps
    • Contour mapping of 2-dimensional patterns
    • Ab-initio direct-method solution of incommensurate one-dimensionally modulated structures and composite structures of two subsystems using electron or X-ray diffraction data
