A Theory on Image Formation of Electron Microscope

抄録

This article is presented to give a consistent basis to all theories of image formation of electron microscope. The author’s idea is to build up an image of a specimen from images of atoms which make up the specimen. The result obtained by developing this idea indicates that an actual image is composed of two ideal images, one of which shows phase contrast and the other constrast due to scattering absorption. By applying this result, bright and dark field images are explained. Not only images of amorphous specimens but those of crystalline specimens are treated.
