WAVIMG

The program WAVIMG is used to calculate high-resolution TEM images from exit-plane wave functions. The program reads wave functions and outputs images or modified wave functions.

The program is controlled by a parameter text list and command-line options. Further details are given in the file howto wavimg.txt.

Image-plane wave functions are calculated by applying electron-optical transfer functions, i.e. imaging aberrations and an aperture. The image intensity is calculated by taking the absolute square of the wave function and including the effects of partial coherence of the electron beam. The image contrast may be attenuated further by a frequency modulated detector transfer function (MTF) and vibration dampening.

Examples

Simple program call with parameter file

wavimg -prm prm\wavimg.prm

Using a specific output file name and setting image defocus from the command-line

wavimg -prm prm\wavimg.prm -out img\TEMimage_foc-4.6nm.dat -foc -4.6
