STEM correction
STEM image acquisition typically requires significantly more time compared to fixed-beam TEM imaging. Due to inherent system instabilities, such as sample drift, the resulting images may exhibit noticeable distortions.
A solution involves capturing two STEM images of the same area with perpendicular scanning directions. The basic version assumes linear drift; the advanced version addresses non-linear instabilities.
