摘　　要：将各向同性的混浊介质材料作为生物组织的光学模型 ,用 2mw单模He Ne高斯激光透过该混浊介质材料 ,测量透射率、偏振度及透射光强的分布 ,得到了偏振度 (v)与透射率 (T)的关系曲线。当透射率T <30 %时 ,偏振度v→ 0 .高斯激光束透过混浊介质材料 ,受散射影响 ,光强偏离高斯分布 ,并提出了透射光强分布公式。The biological organization optics model was bulit up.As 2 mw He-Ne Gruse Laser beam penetrates turbid medium,transmissivity (T),degree of polarization (v) and the distribution of transmitted light intensity were measured and obtained the relation curves among them.Then found v→0 as T<30%.The Gruse light beam through turbid medium was affected because of scatting,light intensity departured Gruse distribution.The distribution law of transmitted light intensity was put forward.
