Scattering and absorbing characteristics of rabbit arteries and veins in Kubelka-Munk model at 488.0nm wavelength of Ar+ laser in vitro

The diffuse reflectance and transmittance of rabbit arteries and veins are studied with the help of Ar+ laser.The measurements are performed with two standard integrating sphere systems.Based on Kubelka Munk model and experiments,the absorption coefficient,scattering coefficient and the changes of total optical intensities I(x),forward scattering flux i(x),backward scattering flux j(x) as a function of thickness of rabbit arteries and veins have been evaluated and analyzed.Measurement results show that there is significant difference of reflectance and transmittance between arteries and veins at 488.0nm wavelength of Ar+ laser.At the same time,the absorption coefficient of arteries is obviously lower than that of veins and the scattering coefficient is much higher than that of veins.Although total optical intensities I(x),forward scattering flux i(x),backward scattering flux j(x) are functions of thickness of rabbit arteries and veins respectively,there are obvious difference between arteries and veins.
