**7. Conclusion**

We describe the Mueller matrix polarization discrimination (MMPD) technique for characterization of highly scattering media(soybean oil) through laser beam. In our experiments, the scattering regime was adjusted to be at the incipient transition between single and multiple scattering. From an experimental standpoint the scattering is most challenging and on the other hand, it is rich in information content because the low-order scattering events are responsible for non-trivial polarization features.

backscattered light and Mueller matrix of bialogical tissues measured with optical

demonstrate that the Mueller matrix components satisfy symmetry relations. These measurements provide detailed information about the changes in the magnitude and sign of Mueller matrix components. This should offer more insight and could lead to novel procedures for characterizing scattering phenomena. We discuss the entire experimental measured Mueller polarized matrix in detail for extracting the taking information about the structure, size, and shape of the scattering particles in term of its output polarization. This has the potential of characterization of turbid sample for their optical properties through polarized laser radiations.

We concluded that soybean oil is optical active, less retardence and highly depolarizing. All these characteristic describe soybean oil an accurate tissue like phantom with low absorption and higher scattering coefficient. Further study and characteristic of soybean oil can be deduced with application of Raleigh and Mie scattering models.
