Abstract
A method of layer-by-layer heterodyne analysis of volume optical media is described. The results of theoretical evaluation, computer modeling, and experimental investigation of the dependence of the maximum speed of analysis of the parameters of the optical circuit and medium are given. The effect of the analysis speed on the resolution of the method for the thickness of the optical medium and on the nature 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. Results are confirmed experimentally.
