Abstract

Results of computer simulations of light diffusion and absorption in hypothetical silver halide light-sensitive layers containing various amounts of a dye are presented. A stochastic computer model is based on a Monte Carlo method [1] – [5]. Appropriate modification of this method allows us to determine an optical modulation transfer function of the layer and a vertical distribution of light absorbed by silver halide in the presence of dye [6], [7]. Isotropic scattering of light is assumed for Ag-Hal crystals. A simple model of characteristic curve [8] is utilized for analysis of a dependence of basic sensitometric parameters on the relative dye concentration. General structurometric advantages and sensitometric disadvantages of the dye addition in a heterogeneous light-sensitive layer are discussed.
