中文摘要：

基于微偏振片阵列（MPA）的偏振成像设备在体积、重量、功耗等方面的优势,极大促进了偏振成像的应用领域。但目前对于MPA光栅参数设计、单元排布模式以及偏振特征解算等方面的研究均存在严重不足,影响了准确偏振特征的获取。针对这些问题,文中利用光栅衍射和等效介质理论进行MPA光栅参数设计,并提出MPA在频域内的联合编解码设计方法,以期MPA单元排布与偏振特征解算达到综合最优。仿真结果表明,MPA编解码设计方式的选择将会对偏振信息的获取性能产生较大影响。

英文摘要：

Micro-polarizer array （MPA） imaging technology has special advantage in equipment volume, weight, real-time imaging etc. All these advantages expand the application of polarization imaging. But little research has been done on how to design MPA parameters, and how to arrange MPA cells, and how to calculate polarization parameters from acquired images. In order to solve this problem, the study of micro-polarizer array （MPA） imaging was carried out in this paper, the grating diffraction and equivalent medium theory were utilized in the design of the relevant parameters for MPA, and a joint coding and decoding design method in frequency domain for MPA was also put forward. The simulation results reveal that the choice of the design method for joint coding and decoding of MPA will have a significant impact on the acquisition performance of polarization information.
