Abstract

Polarisational properties of light scattered in turbid media are considered in this paper. First approximation of these media is the model of suspension which includes the group of scattering centres with these same optical properties given by a complex refractive index and various sizes characterised by a size distribution. If any turbid medium is lightened by partly polarised beam of light described by the Stokes vector then the light scattered on the centres might be polarised too. Stokes vectors of incident beam together with scattered beam are connected by sixteen elemental scattering matrix. On the assumption that turbid medium fulfils limitations of the Mie theory (spherical and homogeneous particles and lack of absorption of exterior medium) scattering matrix is reduced to four independent elements. The group of algorithms based on the Mie solution which allow to model those four elements of the scattering matrix was created in the MATLAB. The results of this modelling for an oil emulsion in synthetic seawater are presented.
