Evaluation of the maximum speed of layer-by-layer heterodyne analysis of light scattering characteristics in volume optical media

Abstract

A method of layer-by-layer heterodyne analysis of volume optical media is described. The results of a theoretical evaluation, computer modeling, and experimental investigation of the dependence of the maximum speed of the analysis on the parameters of the optical circuit and medium are given. The effect of the analysis speed on the resolution of the method along the thickness of the optical medium and on the pattern of the dependence of the output signal on the depth of the studied layer is evaluated. A method for increasing the maximum scanning speed is proposed. The obtained results are confirmed experimentally..
