Phase-Contrast Images
Abstract We see phase contrast any time we have more than one beam contributing to the image. In fact, whenever we say “fringes,” we are essentially referring to a phase-contrast phenomenon. Although we often distinguish phase and diffraction contrast, this distinction is generally artificial. For example, as we saw in Chapters 23 and 24, even thickness fringes and stacking-fault fringes are phase-contrast images although we usually think of them as two-beam diffraction-contrast images.
