Investigation of the transmission matrix of an isotropic scattering medium outside the zone of the probing light beam

摘要

The regularities of change elements of the matrix transformation in scattering media from its optical-geometrical coordinates outside the geometric area of the beam were studied in present paper. On the basis of this investigation we can estimate that. In the coordinate system of the optical thickness along the direction beam propagation and in the orthogonal direction of light field in the scattering medium (outside the exploratory beam), the points with maximum values of the light beam intensity and the degree of linear polarization coincide with each other. Outside the beam geometric area, the increase of absorption in the medium leads to the decrease in the maximum of the total intensity from the optical thickness and the shift of the location of the maximum towards larger ones. Zone of the light beam from which the maximum intensity of the scattered light is realized has a clearly defined optical coordinate depending on the geometry of the experiment.
