The magnetic contrast images of a soft magnetic metallic glass Fe79Si6B14Cu1 subjected to a periodic magnetic field were recorded with a scanning electron microscope by using a stroboscopic technique. An image processing method for the extraction of domain patterns from these images is presented. By this technique, delicate details of the dynamic magnetization process can be investigated and differences in the local magnetisation and domain wall movement can be analysed.
