Abstract

The results of computer simulation of the effects of light scattering in a system composed of single silver halide light-sensitive layer coated on a transparent base are presented. The scattered light penetrating the base film can suffer from internal reflection from its lower surface and thus contributes to some loss of image sharpness. This effect, called reflex-halation, is very disadvantageous. The qualitative dependence of the MTF curve of the system on its geometric and optical parameters is examined. It has been shown, among others, that the deterioration of image quality is stronger for the thinner light-sensitive layer and is more elongated for the elementary scattering indicatrix of silver halide crystals. The result is similar to that obtained in the case of crossover effect, though in the presence of the antihalation layer the observed dependences are opposite to those just mentioned.
