| 摘 要： | Mueller矩阵偏振成像能够全面表征被测样品物的偏振信息,从而成为获取被测样品内部微观结构信息的重要测试方法.利用双旋转波片原理搭建了后向散射Mueller矩阵偏振显微成像系统,并结合新的数据处理算法实现对各向异性植物组织的Mueller矩阵显微成像.针对植物样品的Mueller矩阵的二维分布图像及极化参数图进行分析,并在不同时间进程下通过观察各极化参数图对植物样品的变化进行监测.实验结果表明:相较于普通强度成像,Mueller偏振参数成像可以更加灵敏地反映被测样品的微观结构变化.

| Abstract: | Mueller matrix imaging, which contents the full polarization information of samples under test, has become an important way to investigate the inner micro-structure of the sample. Based on dual rotating waveplates, a Mueller matrix polarization microscopy imaging system is designed to measure the Mueller matrix images of an anisotropic plant tissue, combining with a novel data processing algorithm. The Mueller matrix imaging and polar decomposition parameters are analyzed, and the changes of plant tissues are monitored by observing the imaging of decomposition parameters. It shows that Mueller matrix imaging are more sensitive to the micro-structure of plant samples, comparing with the traditional intensity images. |
