Abstract

This disclosure relates to a method and apparatus for producing multiple pixel-by-pixel simultaneous and overlapping images of a sample in a microscope with multiple imaging beams. A scanning electron microscope, a focused ion-beam microscope, or a microscope having both beams, also has an optical microscope. A region of interest on a sample is scanned by both charged-particle and optical beams, either by moving the sample beneath the beams by use of a mechanical stage, or by synchronized scanning of the stationary sample by the imaging beams, or by independently scanning the sample with the imaging beams and recording imaging signals so as to form pixel-by-pixel simultaneous and overlapping images.
