    Abstract:

    Two-beam coupling in photorefractive BaTiO(3) is used to perform time differentiation of time-varying coherent phase and amplitude images. Differentiation of one-dimensional signals and two-dimensional images is performed.

    Phase Contrast and Differential Interference Contrast Microscopy

    Phase-Contrast Microscopes
    In-phase-contrast microscopes, interference between light directly passing through a cell and light refracted by cellular components is used to create high-contrast, high-resolution images without staining. It is the oldest and simplest type of microscope that creates an image by altering the wavelengths of light rays passing through the specimen. Altered wavelength paths are created using an annular stop in the condenser. The annular stop produces a hollow cone of...
