摘    要:为适应日益增长的对生物细胞形态精密测定的技术需求,应用VirtualLab虚拟仿真实验系统,根据红细胞(RBC)的形体特征和光学特性,设计了双曲面旋转对称体的红细胞光散射模型。最佳组合选用了仿真系统中的运算功能模块,仿真了球形模型和双曲面旋转对称模型下,红细胞在几种典型光源入射情况下的光散射,并获得了这几种典型情况下的前向光散射强度图样、幅值分布曲线和相位分布图。其中生物细胞光散射相位分布局域图表明了相位分布与细胞的形态与结构以及其在光路中的位置密切相关。生物细胞前向光散射相位分布图谱可望成为一种新的测定细胞类别的判读依据。

关 键 词:测量  生物细胞  虚拟仿真  光散射  相位分布

Abstract:To meet the demands of precise measurement of cell profile, the VirtualLab system was applied and a processing function of interfaces transmission was chosen. First, a double curve symmetrical model is designed out based on the character of red blood cell (RBC) in its shape and light scattering. In addition to this, several RBC scattering imitations are made after spherical and no-spherical models under some different light source and situation. Finally, these forward scatting patterns, scattering distribution of amplitudes and distribution of phase are all obtained with the VirtualLab system. The phase distribution in the field shows the correlation between cell′s shape, framework and situation with them. The forward scattering phase distribution of RBC is expected to become a new tool to discriminate cells.
Keywords:measurement  biological cell  virtual simulation  light scattering  phase distribution
