Experimental demonstration of vortex phase-induced reduction in scintillation of a partially coherent beam

Abstract:
We carry out experimental measurement of the scintillation index of a partially coherent beam-carrying vortex phase (i.e., Gaussian-Schell model vortex beam) propagating through thermally induced turbulence. It is demonstrated that a Gaussian-Schell model vortex beam has appreciably smaller scintillation than a Gaussian-Schell model beam, which will be useful in free-space optical communication.

Interference and Diffraction

Interference is a characteristic phenomenon exhibited by waves. When two electromagnetic waves interact with their peaks and troughs coinciding, a resulting wave with enhanced amplitude is produced. This is known as constructive interference. In this case, the two waves interacting are in phase with each other.

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...
