Abstract
An image acquisition method is provided for use in an electron microscope for scanning a sample by an electron probe and acquiring a scanned image. The method includes the steps of: raster scanning a region of the sample under observation with the electron probe and obtaining a first scanned image; raster scanning the region under observation with the electron probe and obtaining a second scanned image; and superimposing the first and second scanned images over each other. In the step of obtaining the first scanned image, each one of scan lines is drawn with the electron probe in a first direction and then moved in a second direction perpendicular to the first direction. In the step of obtaining the second scanned image, each one of the scan lines is drawn with the electron probe in the first direction and then moved in a third direction opposite to the second direction.
