The results of computer simulation of the outcomes of scattering, fluorescence and absorption of actinic light inside the hypothetical light-sensitive layer containing the silver halide crystals and fluorescent substance are presented. It has been assumed that the modelled layer is exposed exclusively to the radiation of the wavelength belonging to the intrinsic sensitivity range of silver halide. The quantitative dependence of the effective light absorption by the silver halide on the fluorescent substance concentration, the layer thickness, quantum efficiency of fluorescence and the ratio of the absorption probability of a photon of wavelength belonging to the sensitized sensitivity range and the absorption probability of a photon of the wavelength from the intrinsic sensitivity range has been examined. Also, the dependence of the modulation transfer function curve on the above parameters has been studied. The results obtained indicate that under some circumstances an addition of fluorescent substance can enhance the photosensitivity of the layer and improve simultaneously the sharpness of the recorded image.
