| dc.description.abstract | This project presents the technique and method of modelling of scattering and absorption by phantom tissue. Absorption and scattering are two fundamental optical properties for turbid biological media. In a homogeneous world, light propagates as a ray; along a straight line with constant speed. Turbid media are the opposite of homogeneous media; a dense concentration of par ticles causes random inhomogeneities that scatter and prevent a straight propagation of light. The sample with high transmittance is high scattering and a higher optical absorption is less a ected by scattering. Through data analysis,the results was determined through the di usion approximation of Radiation Transport Equation Finally from Laser light scattering, scattering and absorption coe cient was described below. For bora milk and skimmed milk ( 0 s = 0:562; 0:364), ( s = 3:527; 2:042) and (g = 0:86; 0:84) respectively. And the value of absorption coe cient is zero. From this result we conclude that scattering dominates on absorption. This is due to high suspension of fat globules in milk which results high scattering | en_US |
