| Abstract: | Based on the radiative transfer equation and the basic theory of multiple scattering,in the Fraunhofer-approximation,the light intensity of multiple scattering through a medium with the particles were calculated.The influences of the optical thickness on the multiple scattering were studied.The characteristics of angular distribution of the scattering intensity,the dependences of the intensity on the optical thickness,and the errors conducted by single scattering were obtained.It provides the theoretical foundations for the optical measurement of actual medium with the particles. |
