Abstract

In the work a method of determination factor anisotropy of the single scattering of biological tissue was described. This method bases on determination the indicatrix of multiple scattering from thick samples in several symmetrical intersections of spatial distribution of radiation obtained experimentally. Some versions of technical realization the system of spatial photometry biological tissue for determining the multiple scattering indicatrix are proposed. Experimental research of anisotropy scattering are presented for etalon samples (milk glass thickness of 1, 3 and 5 mm) and samples of biological tissues (muscles of porcine and chicken thickness 1,4 ± 0,02 mm and 0,76 ± 0,02mm, respectively). The influence of axial asymmetry of factor anisotropy scattering biological tissue’s on the accuracy of the optical coefficients of diffuse reflection and transmission are presented by modeling of Monte Carlo method.
