Influence of space limited of the dispersion medium on image quality characteristics

Influence of space limited of the dispersion medium on radiation distribution and the quality characteristic of image obtained through dispersing medium of the finite sizes is investigated. The way of calculation of boundary function and contrast function of a light strip is determined. It is shown, that space limited of the dispersion medium and illumination conditions render significant influence on image quality -characteristics

The research of layered dispersion media reflectance

The authors have considered the radiation transfer in triple dispersion media with reflective surface. The analytic expressions for determining the values of reflectance and transmission coefficient of dispersion media consisting of three plane layers limited by the reflective surface were obtained. It was shown that stratosphere and bottom atmospheric layers even at low value of optical density and its weak change impact considerably the reflectance of the system "triple media - reflective surface" at all magnitudes of substrate reflection coefficient. It was ascertained that the increase of elongation degree of scattering radiation indicatrix in a cloud layer results in reflectance decrease of the whole dispersion media; this effect is similar to reduction of optical density of atmosphere cloud layer
