Abstract

The polarization properties of light backscattered from the Intralipid suspensions are investigated for different input polarized light. The Stokes vector of the diffuse backscattered light exiting the sample is measured by use of CCD experimental setup. The backscattering intensity and the degree of polarization are calculated from each Stokes vector. Especially, the emphasis is on the influence of linearly polarized light with different input azimuth angle, the circularly polarized light with the different rotary direction on the backscattering intensity and the degree of polarization of the turbid media. Furthermore, both the relations of the backscattering intensity with the media concentration and the degree of polarization with the media concentration for different input polarization state, different input azimuth angle are presented. These experimental results have shown that the degree of polarization and the intensity of light backscattered from a turbid media are sensitive to the input polarization state and the media concentration.
