    摘要: Methods, devices and systems for estimating polarization characteristics of materials based on partial polarimetry are described. One example method for estimating polarization characteristics of a material includes illuminating the material with incident light, which can be unpolarized or have a particular polarization state. Two polarimetric measurements are conducted based on the interaction of the incident light with the material. The two polarimetric measurements detect light having orthogonal polarization states, and the interaction of the incident light with the material includes a depolarizing interaction. The method additionally includes determining an estimated coherency matrix eigenvalue and an estimated Mueller matrix throughput parameter using the first and the second polarimetric measurements, and determining an estimate of a full depolarizing Mueller matrix by extrapolating a reduced-rank Mueller matrix to obtain all sixteen elements of the depolarizing Mueller matrix that identifies the polarization characteristics of the material.
