Abstract:
An experiment is described that directly compares the degradations, with the number of scattering mean free paths, of two field correlations that may be used to form gates for imaging techniques in scattered light: the correlation of the scattered wave with an unscattered reference wave and the correlation of two wave-vector components of the scattered wave itself. Results for 20-microm polymer spheres show that the latter correlation is consistently larger well into the multiple-scattering regime (up to 10 mean free paths) for wave-vector separations less than at least 50 mm(-1) and that the two correlations tend to merge in this scattering regime for larger wave-vector separations.

Electric Field of a Non Uniformly Charged Sphere
Consider a non-uniformly charged sphere, for which the density of charge depends only on the distance from a point in space and not on the direction. Such a sphere has a spherically symmetrical charge distribution. Here, the electric...

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...
