| 摘要近年来，国外对偏振成像技术（尤其是全偏振态的成像技术）的研究非常重视。偏振成像技术把信息量从三维（光强、光谱以及空间）扩充到七维（光强、光谱、空间、偏振度、偏振方位角以及偏振椭率） 。偏振作为信息调制的载体， 能直观地得到观测点的详细偏振数据信息，在天文、医药和遥感领域领域具有重要的应用价值。本文对偏振成像技术进行了理论研究，包括斯托克斯参数的推导和计算；也对偏振成像理论根源及现有的系统结构进行了介绍，包括分测量个数以及分光的特性进行了总结。选取结构简单，最优化可行的方法，并进行实验。最后，对实验可能带来的误差进行了理论上的分析。60456 毕业论文关键词 偏振成像 偏振度 信息调制 斯托克斯参数 Title Research on full Stokes imaging polarimetryAbstractIn recent years, foreign researchers pay much attention to the polarizationimaging technology (especially imaging technology in full polarization).The technique of polarization imaging expands the range of informationboundary from three dimensions (intensity, spectrum and space) to sevendimensions (intensity, spectral, spatial, degree of polarization, angleof polarization and the ellipticity of polarization). As a carrier ofpolarization information modulation, polarization imaging technology canget the detailed polarization data information of observation pointsdirectly. It has been widely used in astronomy, medical imaging and remotesensing. This thesis analyses the theory of polarization imagingtechnology, including the derivation and calculation of Stokes parameters.Besides, polarization imaging root theory and the existing systemstructure are introduced, including the number and the features of measuredparameters. The most simple and optimized feasible method are applied tothe experiment. Finally, the consideration of some probable errors isanalyzed theoretically.
