Comparison between measured and calculated contributions of multiply scattered radiation to the transmittance of a light beam through a turbid medium

Results are presented of measurements pertaining to multiple scattering effects on the propagation of a HeNe laser beam through suspensions of latex spheres in water. Both spheres with a large radius in comparison with the radiation wavelength and spheres with a small radius were used. The data are compared with numerical results obtained by means of a Monte Carlo method employing scaling relations. The effect of varying the distance between the diffusing medium and the receiver was examined.
