高分辨快拍穆勒矩阵成像测偏技术研究

Mueller matrix imaging polarimeter (MMIP) which combined with the function of the camera and polarimeter, can simultaneously obtain the target intensity image and Mueller matrix image, and provide the information of the target, such as the image, organization structure, dielectric constant, water content, these information have important application value, such as in biomedicine, remote sensing, materials, fire and other fields. In order to solve these problems that time-sharing MMIP cannot real-timely and rapidly acquire the polarization information of dynamic or static target, and polarization information inversion in frequency domain results in low spatial resolution. We put forward the new principle and scheme of the snapshot Mueller matrix imaging polarimeter using modified savart polariscope (MSP-SMMIP) and its polarization information inversion in spatial domain. First of all, MSP-SMMIP forward process will be analyzed by the optical theory, its forward mechanism will be clarified, forward mathematical model will be built, the experimental device will be set up, the correctness of the principle scheme will be verified by simulation and experiment. Secondly, the spatial modulation and linear superposition principle will be used to build high resolution inversion model in spatial domain, inversion algorithm will be designed, inversion programs and software in spatial domain will be developed, the efficiency of the algorithm will be validated by simulation and experiment. The project will provides new ideas and new methods for the snapshot Mueller matrix imaging polarimeter, and carry on the beneficial exploration that break through bottleneck that a wide range of applications of the technology restricted low spatial resolution.
