Digital Inline Holographic Microscopy (DIHM) of Weakly-scattering Subjects
Published on: February 8, 2014
Abstract:
A holographic technique by which two dissimilar optical fields can be subtracted to yield only their difference is presented. The principle underlying this technique is that of optical interference between a holographically reconstructed field and a direct real-time one. Experimental verification is presented for the three cases of image-plane, fourier-transform, and Fresnel side-band holograms. Also considered is the application of this concept to change detection between photographic transparencies of some scene taken at different times.

Phase Contrast and Differential Interference Contrast Microscopy
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...
