红细胞的几种光学近似模型及其光信息分布特征

Several Optical Approximate Model and Light Message Distribution Characteristics of Red Blood Cells

根据红细胞(RBC),最佳地选择了球、核式和盘式光学模型,应用光散射理论和光学虚拟仿真技术,分别研究了这3种模型下光散射幅值和相位的分布特征,发现红细胞的光散射全息信息,尤其是相位分布特征与真实细胞的形态密切相关,也就是说,由细胞的相位分布特征完全可以解析出其形态结构。因此,无需进行细胞的三维重建就可以直接由细胞的相位分布特征对细胞进行模式识别和分类检测。

Based on the characteristics of both amplitude distribution and phase distribution in cell′s scattering,which is based on the optical characteristics of three models they are sphere;nuclear and disc-type models for red blood cells （RBC）. Considering the actual optical characteristics of cells,the light scattering theory and optical virtual simulation technology are applied. The results show that the scattering hologram of cells,especially the phase distributing properties,is closely related with the cell morphology. In other words,the phase distributing properties can resolve the cell morphology. Therefore,the cells can be directly recognized and sorted by the phase distributing properties and cann′t need for patterns reconstruction of cells three-dimensional.
