Fringe formation in two-wavelength contour holography
Abstract:
This paper presents a description of fringe formation in two-wavelength contour holography. Approximations are introduced primarily by restricting the recording wavelength difference with the aid of a tunable dye laser and by observing the contour fringes through a controlled viewing system aperture. Several holographic recording and readout arrangements are presented for which explicit and conveniently interpretable contour fringe formulations are derived. Finally, the results from a set of experiments performed with each of the arrangements are offered as experimental evidence supporting the analysis.

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...
