摘　　要：本文通过研究线偏振光照射在生物组织表面时其散射光的偏振态特性 ,基于实验结论 ,提出了一种非接触方法进行生物组织后向散射光信号拾取的方法 ,既克服由接触测量带来的压力和温度的影响 ,又有效减小表面反射光对测量的干扰。并对此进行了实验验证 。The polarization characteristics of the reflectance generated by putting the linear polarized light into the surface of biological tissue, is discussed. Based on the experimental results, a non contact acquisition method is presented. It can not only get rid of the influence of contact pressure and temperature difference between tissue and probe, but also efficiently remove the influence of regular reflectance. We proved these through experiments, whose results demonstrated that the design is rational and feasible.
