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.
