摘要：

The shadow image formed in a scanning transmission electron microscopy (STEM) instrument when no objective aperture is used may provide a convenient means for the alignment of the instrument column, for the correction of astigmatism, for focussing and for calibration of the various instrumental parameters including defocus and spherical aberration. The procedures are illustrated by shadow images recorded from a fluorescent screen in an HB5 instrument, viewed by means of a television camera. © 1979 North-Holland Publishing Company.
