If we are studying the structure of a material, when all is said and done, all we have to show for our expensive electron microscope, hours of specimen preparation, and careful alignment, etc., is an image, a diffraction pattern, or a spectrum. These images and diffraction patterns, which are just different distributions of electron intensity, have first to be viewed in some manner. After viewing, we have to decide if we want to save the result for future reference, perhaps so we can print it for a technical report or scientific publication. Since, as we noted in the opening chapter, our eyes are not sensitive to electrons, we have to find ways to translate the electron intensity distributions into visible-light distributions. This chapter will explain how we “see” electrons.
