La visibilidad en atmosfera heterogénea y su dependencia de las fluctuaciones de la permeabilidad eléctrica.

Abstract

The heterogeneity of a real atmosphere is produced by the densities and radius of the different particles, which give fluctuations of the electrical permeability of the medium. Therefore, the formula of Koschmieder for homogeneous media will not be applicable to a heterogeneous atmosphere in which the meteorological conditions are not stationary. In this work, using the electromagnetic theory of light, the influence of the fluctuations of the electrical permeability on the coherence of a light wave is shown. Expressions for the visibility of the interference fringes according to the definition of Michelson are obtained. Finally, the time average gives an expression that shows how the visibility of the interference fringes and the coherence of a light wave depend on the fluctuations of the electrical permeability of the medium.
